2015-11-01T10:56:00.001+05:30

There are millions of free and open source projects available, many of them better than any commercially available product. Below is a short listing of what we think is the best out there, broken down into ten categories.

//Note:Click the name of the software will directs to the download page//

Antivirus and malware protection:

------------------------------------------

Most PC users realize that they need protection on their computer or may have an installed antivirus program from their computer manufacturer. What most don't realize is that there are free programs that are just as good and in some cases better than the commercial products. Below are our recommendations.

Antivirus program: Avast! or AVG

Malware and Spyware protection: Malwarebytes

Backup solutions:

----------------------

There are dozens of free and commercially available backup programs for computers. Unfortunately, many of those backups are stored locally, meaning if your house were to catch fire, get robbed, or if you lost your backup discs all your data would be lost. This is why when dealing with important data we suggest users use online backup services.

Online backup solution: Mozy or Dropbox

Browsers:

-------------

Although Microsoft Internet Explorer comes pre-installed on Windows computers. There are several excellent free alternatives that everyone should try. These free alternatives can often be faster, have more options, and in many cases be more secure than Internet Explorer.

Internet Browser: Mozilla Firefox or Google Chrome

Compression utility:

-------------------------

When downloading files on the Internet you'll eventually encounter a .zip, .rar, or other compressed file. Dealing with these files can be easy with our below free file compression utility.

File compression utility: 7-Zip

Disc ripper and creation utility:

--------------------------------------

Creating an audio or data CD/DVD, ripping the data from an audio CD, or creating a CD from a .ISO file can also be done freely using our below free recommendation.

CD burner utility: CDBurnerXP

E-mail:

---------

E-mail is yet another service that can be done freely. Most users today use online e-mail solutions like the one listed below. However, for those still using an e-mail client such as Microsoft Outlook we strongly suggest one or both of the below suggestions.

E-mail client: Mozilla Thunderbird

Online e-mail: Gmail

FTP, SFTP, and SSH Utility:

------------------------------------

Users who maintain their own web page or need to upload or download files to or from a server have to use an FTP utility or an SSH client. There are many commercial programs capable of doing this but our below free recommendations beats them all.

FTP client: Filezilla

SSH client: MobaXterm and Putty

Image editor, paint program, and picture organizer:

--------------------------------------------------------------

There are many great free solutions for editing, creating, and organizing your images on your computer. Many of the programs capable of doing these tasks can be several hundred dollars, but all of the below programs are completely free.

Image editor: GIMP

Paint program:Paint.net

Picture organizer: Google Picasa

Multimedia:

---------------

There are dozens of different multimedia programs with different capabilities and limitations. Below are our top free multimedia programs for watching video files and recording audio.

Audio editing and creating tool: Audacity

Video and DVD Player: VLC and MPC-HC

Office Suite:

----------------

An Office suite such as Microsoft Office is often one of the most expensive programs that a user can install on their computer. Why install these expensive programs when there are free solutions that are just as good.

Office suite: OpenOffice

Notepad and Source code editor: Notepad++

உங்கள் கம்ப்யூட்டர்-ல் விண்டோஸ் 10 நிறுவப்போகிறீர்களா? Windows 10 புதிய வசதிகள் என்னென்ன??

2015-08-10T10:31:00.004+05:30

கணினி துறையில் முடி சூட மன்னனாக விளங்கிவரும் மைக்ரேசாப்ட் தனது முதல் இயங்குதளமான எம்.எஸ் விண்டோஸ் 1 கடந்த 1985 ஆண்டு வெளியிட்டது. தற்போது சரியாக 25 ஆண்டுகள் அதாவது கால்நூற்றாண்டு பிறகு விண்டோஸ் 10 இயங்குதளத்தை வெளியிட்டுள்ளது.இந்த 25 ஆண்டுகளில் அதன் வளர்ச்சி அபரிமிதமானது.

எனினும் அதன் முந்தைய வெளியீடான விண்டோஸ் 8 எதிர்பார்த்த அளவு வாடிக்கையாளர்களை கவரவில்லை.

எனவே உடனடியாக ஒரு புதியதை வெளியிட்டாக வேண்டிய கட்டாயத்தில் விண்டோஸ் 10 வெளிவந்துள்ளது.

கடந்த யூலை 29ம் திகதி வெளியிடப்பட்ட விண்டோஸ் 10 வாடிக்கையாளர்களிடம் நல்ல வரவேற்பை பெற்றுள்ளது. வெளியிடப்பட்ட 24 மணித்தியாலங்களில் 1 கோடிக்கு அதிகமானவர்கள் இந்த இயங்குதளத்தை பயன்படுத்தி இருப்பதே இதற்கு சாட்சி.

சரி விண்டோஸ் 10ன் முக்கிய அம்சங்களை பார்ப்போம்:

விண்டோஸ் 7ல் இருந்தது போன்று ஸ்டார்ட் மெனுவை (Start Menu) சிறிதாக மீண்டும் கொண்டுவந்துள்ளது.

மேலும் இதில் இண்டர்நெட் எக்ஸ்புலோரருக்கு (Internet Explorer) பதிலாக கோர்டானா (Cortana) என்ற புதிய செயலியை அறிமுகப்படுத்தியுள்ளது. இதன் மூலமாக உங்கள் தேடல் எளிமையாக இருக்கும்.

ஒரே நேரத்தில் நான்கு அப்ளிகேசன் வரை பயன்படுத்தலாம்.

எக்ஸ்புலோரருக்கு மாற்றாக எட்ஜ் பிரவுசர்(Edge Browser) இணைக்கப்பட்டுள்ளது. இதன் அதிவேக பிரவுசர் மூலம் உங்கள் நேரம் மிச்சப்படும்.

விளையாட்டு பிரியர்களுக்காகவே எஸ் பாக்ஸ் (X BOX) செயலியும் இதனுடன் இணைக்கப்பட்டுள்ளது. இதன் மூலம் ஒரு சிறந்த கேமிங் அனுபவத்தை பெறலாம். சாதாரண கணினியை மட்டுமின்றி தொடுதிரை வசதியுள்ள சாதனங்களையும் மனதில் வைத்து இது வடிவமைக்கப்பட்டுள்ளது.

வாட்ஸ் அப்பை (Watsapp)கணனியில் பயன்படுத்தும் வகையில் வாட்ச் அப் வெப் என்ற சேவையை கொண்டுவர முடிவு செய்துள்ளது.

மேலும் விண்டோஸ் 7 மற்றும் விண்டோஸ் 8 பயன்படுத்தி வந்தவர்கள் இலவசமாக விண்டோஸ் 10க்கு தரம் உயர்த்தி கொள்ளலாம் என்று கூறப்பட்டுள்ளது.

மொத்தமாக பார்த்தால் இதன் முந்தைய பதிப்பான விண்டோஸ் 8 (8.1) விட பல சிறப்பு வசதிகளுடனும் விண்டோஸ் 10 களமிறங்கியுள்ளது.

இன்டர்நெட்டில் "WWW" என்றால் என்ன?

2015-05-17T19:05:00.002+05:30

இன்டர்நெட் இல்லை என்றால் பூமியே சுத்தாது என்று சொல்லும் அளவிற்கு அசுர வளர்ச்சி பெற்று விட்டது.இன்றைய இளைஞர்கள் முதல் பெரியவர்கள் வரை எதற்கெடுத்தாலும் இன்டர்நெட் தான், அதுவும் சமூக வலைத்தளங்கள் பற்றி சொல்லவே வேண்டாம்.

பிரிட்டிஷ் கணினி விஞ்ஞானியும், முன்னாள் செர்ன்(CERN) ஊழியருமான டிம் பெர்னர்ஸ் லீ மற்றும் பெல்ஜிய கணனி விஞ்ஞானி ராபர்ட் கயில்லியவ் இவர்கள் தான் இணையத்தை கண்டுபிடித்தவர்களாக கருதப்படுகிறது.

1989ம் ஆண்டில் டிம் பெர்னர்ஸ் லீ உலகளாவிய வலைக்கு முதல் கட்ட திட்ட அமைப்பை எழுதினார். இது முதலில் செர்ன்(CERN) தகவல் பறிமாற்றத்திற்காக மட்டுமே எழுதப்பட்டது.

ஆனால் இது உலகளவில் சென்றடைய வேண்டும் என்பதை உணர்ந்த பெர்னர்ஸ், 1990ல் ராபர்ட் உடன் இணைந்து மேம்படுத்தப்பட்ட உலகளாவிய வலையமைப்பை உருவாக்கினார்.

இணையம்(Internet) மற்றும் உலகளாவிய வலை(WWW) ஆகிய சொற்கள் பேச்சு வழக்கில் பெரிதும் வேறுபாடின்றி அடிக்கடி பயன்படுத்தப்படுகின்றன.

இருப்பினும், இணையமும் உலகளாவிய வலையும் ஒன்றல்ல.

இணையம் என்பது உலகளாவிய தரவுத் தகவல்தொடர்பு முறைமையாகும். வலை என்பது இணையத்தின் வழியாகத் தொடர்புகொள்ளும் சேவைகளில் ஒன்றாகும்.

இது மிகை இணைப்புகள் மற்றும் URLகள் மூலம் ஒன்றுடன் ஒன்று இணைக்கப்பட்ட ஆவணங்கள் மற்றும் பிற வளங்களின் தொகுப்பாகும். சுருக்கமாக, வலை என்பது இணையத்தில் இயங்கும் ஒரு பயன்பாடு என்றே சொல்லலாம்.

Krish Infotech Cuddalore: Windows 7 Tips

2015-02-15T08:15:00.000+05:30

Have you ever wondered just how some people really get, what seems like, full use of their computer? Sure we all played Minesweeper and wrote the occasional Word document when we first started out using computers. Nowadays computers are a regular part of everyday life. From playing games to communicating with friends and family half way around the globe. Computers are really useful tools, but, all tools can be used in different ways. Here’s a quick top 10 count down on a few tips and info that’ll make your life easier in Windows 7.

10. GOD MODE:

To give you complete control over all the configurable options in Windows at a single press of a button just simply create a new folder anywhere and rename it to this: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} The folder you create will now have 270 items that are to do with configurable options in Windows 7. Interestingly it also works for Windows 8.1 as well.

9. “VIRTUAL” WI-FI:

Windows 7 has a Microsoft Virtual Wi-Fi Miniport adapter located in your network connections. You can use this for making your laptop work as a Wi-Fi hotspot.

8. RELIABILITY MONITOR:

If your computer is being a little strange or if it isn’t doing something it should, or for that matter, is doing something that it shouldn’t then search for ‘reliability’ in the Start menu and open the ‘View reliability history’. This will display a graph of the system’s stability index with the scale 1-10 for a certain period of days or weeks. This should allow you to figure out which program or Windows component is not working as it should.

7. ENHANCED CALCULATOR:

Calculators are great for standard mathematics, but what if you need a to shake things up a little in the science dept? If you click the view menu, you will see that the calculator comes equipped with a number of powerful built-in features; unit conversions, mortgage spreadsheets, date calculations and fuel mileage, etc. Not so standard now, are you?

6. STEPS RECORDER:

If you need remote assistance but the remote access is not working, just search and run “psr” from the Start menu. When you click on the “Start Record” option, the feature starts recording all the activities by an array of screenshots while adding automatic captions. When you end recording, all the recorded data is combined together and then saved as a web browser-compatible MHTML (MIME HTML) file which is kindly pre-zipped and ready to be attached to an email for you to send to your helper.

5. FILE SUPPORT IN WORDPAD:

WordPad can now open ODT or DOCX files. The only downside is that it doesn’t work great with all formatted docs.

4. POWER EFFICIENCY REPORT:

From the Start menu, navigate to CMD and type the following:

powercfg –energy

This will then scan your system for 60 seconds, then a file named energy-report.html will be created in \windows\system32 folder. Just copy it somewhere else before opening it, i.e. your desktop, and it will reveal which settings or devices are zapping power.

3. ERASE FREE DISK SPACE:

When you delete something in Windows, the space they had taken up is labeled as “available for use.” But, the deleted files are still restorable if you use some software until they are overwritten with more data. To resolve this simply, open Command Prompt and type:

cipher /w:Z

Replace Z with the letter of the drive/partition you wish to erase. Be patient, it takes time.

2. FOLDERS ON YOUR TASKBAR:

Programs can be pinned to the task bar and are useful there, right? This is how you can keep the folders. Just drag a folder to the empty space on the Taskbar and then release the button once the “Pin to Windows Explorer” pops up. Now every time you right click the Windows Explorer button, you will have access to the folder via Jump List.

1. HOTKEY WINDOWS BETWEEN MONITORS:

To do this, just hold onto the Windows key and press left or right arrow and your active window will then be anchored in that direction. This happens on every monitor that you have and if you use Windows + Shift +Left/Right Arrow key, the active window will jump to the second monitor.

So there you have it, a few tips to keep you occupied for a while. Enjoy.

Krish Infotech Cuddalore: Make your Computer Talk...

2015-01-15T03:50:00.000+05:30

Have you ever wondered how can you make your computer speak whatever you input to it like in the movies? Would it not be fun? If only it was possible! Rejoice, because now it is possible. Well, if you wish to know how to do this, then you have come to the right place. With this trick, you can create a script in Windows which will make your computer speak whatever you input to it.

To create one such talk script, follow the steps given below:-

Steps
1) Open Notepad.
2) Copy and paste the exact code given below.

Dim Message, Speak
Message=InputBox("Enter text","Speak")
Set Speak=CreateObject("sapi.spvoice")
Speak.Speak Message

3) Click on File Menu, Save As, select All Types in Save as Type option, and save the file as Speak.vbs or "*.vbs".
4) Double click on the saved file, a window will open like the one in the image. Enter some text in enter text column and click OK.

Now your Computer will speak / talk what you typed in Step 4. Try it yourself.

Windows Compatibility: This VBS file can be executed on all versions of Windows including Windows XP, Windows Vista, Windows 7 and Windows 8.

(or by another method)

Step 1: Open Notepad

Open up Notepad on your windows xp, windows 7, or windows 8 computer.

Step 2: The Code

Type this into Notepad:

Dim text, sapi
text=inputbox("enter text to be spoken")
Set sapi=Createobject("sapi.spvoice")
sapi.Speak text

Now what does this mean?
-When you execute this script it first creates a input box which is recognized as "text".
-Then the script sets up the sapi so we can now use it (this what will speak)
-Lastly it takes what was typed into input box "text" and sends it to the sapi to be spoken.

Step 3: Save Your File

Now you need to save your file.

First Click file>save as...

Next choose any file name but be sure to put .vbs afterwards. Ex. Filename.vbs

Then be sure to click next to Save as type: and then in the drop down menu click All Files

Click save.

Step 4: Execute Your File

The last step is to locate where you saved your file and double click it.

In the input field enter something and click ok.

Congratulations! You just made your computer talk!

Other notes:
• this is written in a Visual Basic scripting language (vbs)
• this only works with windows xp and higher
• if your having trouble or have questions feel free to ask me in the comments.

Cuddalore Krish Infotech: Parts of a computer

2015-01-01T07:34:00.000+05:30

If you use a desktop computer, you might already know that there isn't any single part called the "computer." A computer is really a system of many parts working together. The physical parts, which you can see and touch, are collectively called hardware. (Software, on the other hand, refers to the instructions, or programs, that tell the hardware what to do.)

The following illustration shows the most common hardware in a desktop computer system. Your system might look a little different, but it probably has most of these parts. A laptop computer has similar parts but combines them into a single, notebook-sized package.

System unit

The system unit is the core of a computer system. Usually it's a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another component is random access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

Almost every other part of your computer connects to the system unit using cables. The cables plug into specific ports (openings), typically on the back of the system unit. Hardware that is not part of the system unit is sometimes called a peripheral device or device.

Storage

Your computer has one or more disk drives—devices that store information on a metal or plastic disk. The disk preserves the information even when your computer is turned off.

Hard disk drive

Your computer's hard disk drive stores information on a hard disk—a rigid platter or stack of platters with a magnetic surface. Because hard disks can hold massive amounts of information, they usually serve as your computer's primary means of storage, holding almost all of your programs and files. The hard disk drive is normally located inside the system unit.

CD and DVD drives

Nearly all computers today come equipped with a CD or DVD drive, usually located on the front of the system unit. CD drives use lasers to read (retrieve) data from a CD; many CD drives can also write (record) data onto CDs. If you have a recordable disk drive, you can store copies of your files on blank CDs. You can also use a CD drive to play music CDs on your computer.

DVD drives can do everything that CD drives can, plus read DVDs. If you have a DVD drive, you can watch movies on your computer. Many DVD drives can record data onto blank DVDs.

Tip

If you have a recordable CD or DVD drive, periodically back up (copy) your important files to CDs or DVDs. That way, if your hard disk ever fails, you won't lose your data.

Floppy disk drive

Floppy disk drives store information on floppy disks, also called floppies or diskettes. Compared to CDs and DVDs, floppy disks can store only a small amount of data. They also retrieve information more slowly and are more prone to damage. For these reasons, floppy disk drives are less popular than they used to be, although some computers still include them.

Why are these disks called "floppy" disks? The outside is made of hard plastic, but that's just the sleeve. The disk inside is made of a thin, flexible vinyl material.

Mouse

A mouse is a small device used to point to and select items on your computer screen. Although mice come in many shapes, the typical mouse does look a bit like an actual mouse. It's small, oblong, and connected to the system unit by a long wire that resembles a tail. Some newer mice are wireless.

A mouse usually has two buttons: A primary button (usually the left button) and a secondary button. Many mice also have a wheel between the two buttons, which allows you to scroll smoothly through screens of information.

Mouse pointers

When you move the mouse with your hand, a pointer on your screen moves in the same direction. (The pointer's appearance might change depending on where it's positioned on your screen.) When you want to select an item, you point to the item and then click (press and release) the primary button. Pointing and clicking with your mouse is the main way to interact with your computer. For more information, see Using your mouse.

Keyboard

A keyboard is used mainly for typing text into your computer. Like the keyboard on a typewriter, it has keys for letters and numbers, but it also has special keys:

The function keys, found on the top row, perform different functions depending on where they are used. The numeric keypad, located on the right side of most keyboards, allows you to enter numbers quickly. The navigation keys, such as the arrow keys, allow you to move your position within a document or webpage.

You can also use your keyboard to perform many of the same tasks you can perform with a mouse. For more information, see Using your keyboard.

Monitor

A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures.

There are two basic types of monitors: CRT (cathode ray tube) monitors and the newer LCD (liquid crystal display) monitors. Both types produce sharp images, but LCD monitors have the advantage of being much thinner and lighter.

Printer

A printer transfers data from a computer onto paper. You don't need a printer to use your computer, but having one allows you to print e‑mail, cards, invitations, announcements, and other material. Many people also like being able to print their own photos at home.

The two main types of printers are inkjet printers and laser printers. Inkjet printers are the most popular printers for the home. They can print in black and white or in full color and can produce high-quality photographs when used with special paper. Laser printers are faster and generally better able to handle heavy use.

Speakers

Speakers are used to play sound. They can be built into the system unit or connected with cables. Speakers allow you to listen to music and hear sound effects from your computer.

Modem

To connect your computer to the Internet, you need a modem. A modem is a device that sends and receives computer information over a telephone line or high-speed cable. Modems are sometimes built into the system unit, but higher-speed modems are usually separate components.

Easy ways to keep your computer safe on the Internet:

2014-09-09T18:30:00.000+05:30

Introduction

Let's face it, the Internet is not a very safe place. There are hackers trying to access your computer, worms trying to infect you, malicious Trojans disguised as helpful programs, and spyware that reports your activities back to their makers. In many cases those who become infected unknowingly become a breeding ground for unwanted programs and criminal activity. It does not have to be this way. With proper education and smart computing the Internet can be a safe, useful, and fun place to visit without having to worry about what is lurking around the corner.

This tutorial was created to provide tips and techniques for smart and safe computing. When using these techniques you will not only protect yourself and your data from hackers and viruses, but also keep your computer running more smoothly and reliably. The advice in this tutorial applies to all computer users and all operating systems, but we have tried to point out specific steps for various operating systems as it becomes necessary.

What you need to know to keep your computer safe on the Internet

Tip 1: Always install Operating System updates

The most important steps for any computer user is to always install updates, especially security updates, when they become available for your operating system. When operating systems are developed, bugs, or programming errors, are unfortunately created that could cause security vulnerabilities or make your computer act unexpectedly. Though the developers spend many hours trying to prevent these bugs, they are ultimately human, and bugs occur. It does not matter what operating system we are talking about, bugs are always introduced. Due to this, companies will routinely release updates and patches to fix any security vulnerabilities or errors as they are discovered.

In order for your computer to operate smoothly and safely it is imperative that all users install updates, especially security updates, as they are released. By not installing these updates you leave your computer at risk from remote users hacking into them or viruses exploiting these bugs to gain access to your computer. Thankfully, all modern operating system provide easy methods for installing new updates. In fact, most of these methods do all the work for you and just require you to click a prompt to allow the updates to install. Therefore, there really is no reason not to install them.

Below are two tutorials that can be used to learn how to update your operating system in Windows and MacOS:

For Macs: How to install Software Updates on your Mac

For Windows: How to update Windows

Tip 2: Keep your installed applications up-to-date

A common method that computer infections use to infect your computer are security vulnerabilities in your installed programs. Common programs that are targeted due to their large install base are web browsers, Microsoft Office, Adobe Reader, Adobe Flash, Adobe Shockwave, and Oracle Java. In order to make your computer as secure as possible, you need to make sure these programs are updated when new security fixes are released. The problem is that many people just ignore alerts about new updates, even though these updates fix security problems that could allow hackers into your computer.

If you are prompted by a known application that you commonly use stating that there is a new update, just click the button to allow it to be updated. This is especially true for web browsers, which are commonly targeted by malicious code on web sites. If there is a new version of your web browser available, you should upgrade it so that any security vulnerabilities are fixed.

If you use Windows, there is a great program called Secunia PSI that automatically scans your computer for applications and automatically updates them for you. Information about this program can be found at this tutorial:

How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector (PSI)

Tip 3: Do not use the same password at every site

It has now become common to hear about a company who was hacked and the hacker was able to access the company members email addresses and passwords. If you use the same password at every site, and one of those sites was hacked, the hacker now has your account information everywhere that you have an account. They can now login to your email, see what other accounts you have, banks that you use, etc and gather even more private information about you.

It is very important to use a different password at every site where you have an account. Unfortunately, we all know it's not realistic and even possible to remember a different password for every account you may own. To help with that you can use a password management program like Keepass to help you store your account information for each site you login to. Keepass also contains plugins that allow you to automatically login to sites you visit using the information stored in its database.

If you would rather not store your passwords in another program, then creating a standard password format is better than using the same password at each site. For example, for each site you visit you can create a password in the format <year born><sitename>!55. So if you were registering an account at Bleepingcomputer and you were born in 1975, you could use the password 1975bleepingcomputer!55. Then at CNN you could have an account 1975cnn!55. As you can see you are now using a different and strong password at each site, but you have an easy to remember format that you can use to determine the password.

Tip 4: Install and be sure to update your anti-virus software

It is very important that your computer has antivirus software running on your machine. By having an antivirus program running, files and emails will be scanned as you use them, download them, or open them. If a virus is found in one of the items you are about to use, the antivirus program will stop you from being able to run that program and infect yourself.

Is it also important to note that there is no point in running an antivirus program if you do not make sure it has all the latest updates available to it. If you do not update the software, it will not know about any new viruses, trojans, worms, etc that have been released into the wild since you installed the program. If a new infection appears in your computer, the outdated antivirus program will not know that it is bad, and not alert you when you run it and your computer becomes infected. It is imperative that you update your Antivirus software at least once a week (Even more if you wish) so that you are protected from all the latest threats.

It is also suggested that you install a free anti-malware scanner in addition to your normal anti-virus program. These free anti-malware scanners do not offer real-time protection unless you upgrade to the commercial version, but offer excellent detections when scanning with them periodically. Two recommended Windows anti-malware programs are MalwareBytes Anti-Malware and SUPERAntiSpyware. Tutorials on how to use these programs are listed below:

How to use Malwarebytes Anti-Malware to scan and remove malware from your computer

How to use SUPERAntiSpyware to scan and remove malware from your computer

The following link has a list of some online and stand-alone antivirus programs: Virus, Spyware, and Malware Protection and Removal Resources

Tip 5: Use a firewall

The importance of using a Firewall on your computer or on your network cannot be stressed enough. Just because you have all the latest security updates, you are still susceptible to unreported, unpatched, or unknown vulnerabilities that a hacker may know about. Sometimes hackers discover new security holes in a software or operating system long before the software company does and many people get hacked before a security patch is released. By using a firewall the majority of these security holes will not be accessible as the firewall will block the attempt.

For a tutorial on Firewall's and a listing of some available ones, please visit the following link: Understanding and Using Firewalls

Tip 6: Backup your data!

Backing up your data is not necessarily a way of keeping your computer safe, but it is a way of keeping your data safe. As you use your computer there may come a time that you cannot find a document or your hard drive fails. Having a regular backup of your data available saves you from the anguish of losing those hours of work or precious baby photos.

Both Windows and MacOS have free built in backup software so please be sure to use them to protect your data. In Windows, you can use Windows Backup program and Macs have the Time Machine program. If you wish to use a third-party program, we have listed two tutorials below that utilize free backup programs.

How to backup and restore your data using Cobian Backup
How to Backup and Restore your hard drive with DriveImage XML

Tip 7: Enable the display of file extensions

It is important to enable file extensions so you can see the complete file name. A file extension, or file name extension, is the letters immediately shown after the last period in a file name. Many viruses that are sent via email as attachments contain two periods. For example, picture.jpg.exe. Since Windows is by default configured to not display extensions, Windows will strip off the .exe and instead the file will appear as picture.jpg. To you this looks like harmless image file. Once you click on it, though, instead of an image opening, it actually runs the virus and you become infected. Though a Mac hides file extensions by default as well, this is less of a problem on that operating system.

For more information about file extensions and how to show them click here:

How to show File Extensions in Windows
How to show filename extensions on a Mac
What is a File Extension?

Tip 8: Do not open attachments from people you do not know

Don't open an attachment from someone you do not know. Simple as that. If someone you do not know sends you something, just delete it. If you receive an attachment from someone you know well, then you should still never open attachments that end with the following extensions: .exe, .pif, .com, or .bat. For more information about file extensions, please see step 3.

Attachments are a common way that computer infections spread from computer to computer. As described in the previous tip, malware writers exploit default settings on operating systems to make attachments harmless looking so that you will then open them.

If you really want to see the file, first scan it by saving it to a folder on your drive and then scanning it using a site like Virustotal. You can also email the person directly and ask if they actually sent you that file.

Tip 9: Ignore emails that state you won a contest or a stranger asking for assistance with their inheritance

A common online scam are emails from strangers that state that you won a contest or that they need help transferring money or receiving an inheritance. These are all scams where they are trying to get your personal information in order to perform identify theft or want to use you as part of a money laundering scheme. When you receive these emails just delete them.

Tip 10: Watch out for online and phone support scams

Phone support scams are becoming more common and involve receiving a phone call from someone pretending to be from Google, Microsoft, or another large company. They state that they have detected you are having computer problems and are offering free remote diagnostics to see what is wrong. After they take control of your computer and pretend to look at various things, they state that your computer has a lot of problems and then try to sell you a support contact or software. Microsoft, Google, and other large companies will NEVER call you out of the blue and do this. If you do receive a call like this say "No thanks" and hang up.

Just like phone support scams, online support scams are common as well. These scams come in the form of online advertisements that display misleading messages stating that your computer is having an issue. Just like the phone support scams, these are just advertisements from people who are trying to sell you software or services. Just ignore any advertisements and messages you see like this.

Tip 11: Ignore web pop ups that state your computer is infected or has a problem

When browsing the web, it is not uncommon to be shown an advertisement that pretends to be an online anti-virus program. These advertisements will pretend to scan your computer and then state you are infected. It will then prompt you to install a piece of software.

Examples of these types of advertisements can be seen below:

Fake Mac & Windows Online Scanners
Click on each image to enlarge

If you see these types of advertisements, just close your browser to close the message. If you are having issues closing your browser, then you can use the Alt+F4 keys in Windows or the Apple Key+Q in MacOS to force the program to close. If the browser refuses to close, then you can use these guides to help you close the programs:

How to force quit a program on a Mac
How to close a program in Windows

Tip 12: Ignore and close web pop ups that pretend to be a Windows alert

Another tactic some software vendors use is to display web pop ups that pretend to be an alert from your operating system. These alerts look just like a Windows or Mac window, but are instead a web popup trying to get you to click on the ad.

If you see these types of advertisements, just close your browser to close the message. If you are having issues closing your browser, then you can use the Alt+F4 keys in Windows or the Apple Key+Q in MacOS to force the program to close. If the browser refuses to close, then you can use these guides to help you close the programs:

How to force quit a program on a Mac
How to close a program in Windows

Tip 13: Some types of web sites are more dangerous than others

Some types of sites are more prone to distribute malware or use deceptive techniques to have you click on ads. With this said, do not visit porn sites! I know some of you may not be happy about this, but the reality is that many sites in this category happily try to infect machines who visit them.

Other sites that you can commonly become infected from are Warez and Crackz sites. Not only is pirated software illegal, but the sites that distribute them are a breeding ground for malware.

Tip 14: Be vigilant when using Peer-To-Peer Software

Using a program like Bittorrent for legitimate applications is perfectly fine. On the other hand, if you use P2P applications for copyrighted movies or software there is a good chance that they may contain Trojans as well. It is very common for malware developers to distribute malware on P2P networks that pretends to be a program required to view a movie or play a game. Therefore, it is strongly suggested that you do not use Peer-to-Peer software for illegal activities as you will probably get what you pay for.

Tip 15: When installing a piece of software, watch out for "bundled" tool bars and programs that you may not want

A common practice used by free programs is to bundle others programs with them. This allows the developer to offer a program for free, but still earn revenue by bundling tool bars and other software in them. When installing a program, please read through all the prompts and instructions carefully. If you come to a screen where the program is asking if you wish to install another companies tool bar or program, then please do some research as to whether or not you think these programs will be useful to you. If you do not wish to install these bundled programs, then uncheck the option to install them.

On a general note, having too many browser tool bars can negatively affect the functionality of your web browser. As most browsers have built-in search fields that you can customize, there is typically no need to install separate search tool bars unless they contain specific functionality that you would find useful.

Tip 16: When installing a piece of software, read the End User License Agreement (EULA) so you know what your getting into

When you install a piece of software be sure to read the end user license agreement, or EULA, before allowing it to install. By law, an EULA must contain information on how this program will interact with your computer and use your private information. If you find that a particular program is using your personal data or tracking your computer use, then you can use that information to determine if you really want to continue installing the software.

Types of Computer Virus:-

2014-05-29T10:15:00.000+05:30

Boot viruses

Since nobody uses floppy disks anymore, these types of computer virus are left to infect only the master boot records of the hard disk. The boot record program loads the operating system in the memory at startup. These viruses replace the boot record and move it to a different part of the hard disk, or simply overwrite it. As you can imagine, once you start your operating system, it loads into memory, along with the virus. Once the virus is in the memory, it is free to do whatever it was programmed to do. To avoid loading the boot record viruses into memory, you must boot your operating system from another source (another hard drive or a bootable CD/DVD).

Program viruses

These types of computer virus will infect only executable files (with extensions like .BIN, .COM, .EXE, .OVL, .DRV, and .SYS). Once executed, these programs load into memory, along with the virus contained within them. Once in the memory, the scenario repeats – the virus is free to act and infect other files or simply deliver its payload. These viruses are friendlier than boot viruses and can be removed a lot easier.

Multipartite viruses

These computer viruses are hybrids, derived from boot viruses and program viruses. They infect executable files, just like the program viruses but, once the executable is executed, it infects the master boot records. The scenario is similar to the boot virus’s one: once you boot your operating system, the virus is loaded into the memory, from where it is free to infect other programs and replicate itself, ultimately delivering the payload.

Stealth viruses

These viruses are specialized in avoiding detection and will use a number of techniques to do so. Most of them simply redirect the hard disk head, forcing it to read another memory sector instead of their own. Some of them also alter the reading of the file size shown when listing the directory. These types of computer virus are very hard to find by humans, but antivirus software is specially designed to track them down and erase them.

Polymorphic viruses

The polymorphic viruses will always change their source code from one infection to another. Each infection is different, and this makes detection very hard. However, detection is still possible, depending on the antivirus.

Macro viruses

This virus is relatively new and it infects macros within a template or document. When you open a word processing document, it activates the virus. The virus infects the Normal.dot template, which is a general file used by all the documents. So, whenever you open an uninfected document, by referring to the Normal.dot file, it gets infected as well. This infection can only spread if infected documents are opened on another machine.

Active X viruses

Most people do not know how to configure ActiveX and Java controls, unconsciously leaving a security hole. Applets are then allowed to run freely on the machine, delivering all ActiveX viruses. By simply turning off some ActiveX and Java controls in the browser, a user can efficiently protect their PC from this type of computer virus.
