Maintaining your computer

1. Backup, backup backup! Backing up your data just means saving your files to a separate location (like a cd, floppy or zip disk) so in event of disaster you can easily copy your files back onto your computer. How often really depends on you. Just ask yourself "If I only back up once every 3 months, would anything I saved on my hard drive since the last time I saved it on a backup be all right if I could NEVER get it back?"

2. Invest in an UPS (uninterruptible power source). A UPS is a wonderful device that works as a surge protector and a battery backup all in one! Not only does it keep your computer safe from electrical spikes that can be traveling through the lines, it also gives you time to save your work, and properly power down your computer in event of a power failure. You don't lose your work, and your computer gets to be shut down properly.

3. Never turn the computer off with the power switch. The one exception to this rule is when your computer locks up and your hard drive is not running (the hard drive light is not blinking). In this situation, you can turn the power off without harmful effects to the hard drive. As cutting the power can also result in lost data or Windows files, you should only do this when you have to.

Doing this can help prevent permanent hard drive damage caused by the hard drive heads contacting the surface of the drive disc. This can prevent a host of Windows problems.

Whenever possible, recover from crashes by pressing the Ctrl + Alt + Delete keys at the same time and going into your Task Manager. You can often find programs that are not responding in here, and chose to close them from this utility. Press Clt + Alt + Delete again to reboot your computer from this screen.

4. Scan disk and defrag once a month. These utilities help to keep your hard drive in optimal shape and error free.

5. Do not unplug peripheral devices while the power is turned on. Unplugging devices such as your mouse, keyboard, printer etc with the power on can short out the connector socket or even the motherboard itself.

The only time you would unplug something while the power is on, is if the device is hot swappable/pluggable. If you are unsure if something is hot swappable or not, power down first to play it safe.

6. Remove programs from your startup. Often when you install a program, it will ask you whether it should load up as soon as Windows loads (or just decide to do so on its own). The more programs you have trying to start up at the same time, the slower your computer will start. Also, all those programs running in the background while you try to work will slow your computer's response time.

In windows 98, ME, and XP, you can do this by going to your Start -> Run -> in the command box type in 'msconfig' and a small window will appear. Go to the tab marked "Startup" and you can chose what items to remove from there.

In Windows 2000, you can do this by going to your Control Panel -> Administrative Services -> Services.

7. Run virus checks and adware/spyware scans regularly (at least once a week). There are so many types and variations of viruses, spyware and adware floating around that at times it may seem daunting to even have internet access on your computer. However, regular scans with your virus scanner, and adware scanners, can ensure your computer remains healthy.

8. Keep disks handy. If the worst thing happens, and you need to format your system for one reason or another, then it is a good idea to have all your driver disks, operating system disks, backup disks and so forth in a readily available place. Running around in a panic at the 11th hour because you cannot remember where the drivers are for your network card, is not a good place to be.

9. Keep your software updated. Software developers are always writing and releasing patches that update the software you have already bought from them. A lot of these patches fix problems you may be experiencing yourself with a particular program.

Other patches plug security leaks. Still other patches update reference files for your virus/spy/adware scanners to make sure you are scanning for as many variants as possible. So make sure you regularly update/patch your operating system, virus scanners, and various other applications!

10. Develop a schedule of maintenance practices. All this advice is meaningless if you keep forgetting to do it, or only remember after something has gone wrong. Write yourself up a maintenance schedule, with a list of what tasks should be performed daily, weekly, and monthly.

If you develop a routine and stick to it, then you should avoid the larger problems by always being on top of the smaller ones!

What are the Symtoms of an infected computer

It’s not always easy to tell if your computer has been compromised. More than ever before, the authors of viruses, worms, Trojans and spyware are going to great lengths to hide their code and conceal what their programs are doing on an infected computer. That’s why it’s essential to follow the advice given in this guide: in particular, install Internet security software, make sure you apply security patches to your operating system and applications and backup your data regularly.
It’s very difficult to provide a list of characteristic symptoms of a compromised computer because the same symptoms can also be caused by hardware and/or software problems. Here are just a few examples:

Your computer behaves strangely, i.e. in a way that you haven’t seen before.
You see unexpected messages or images.
You hear unexpected sounds, played at random.
Programs start unexpectedly.
Your personal firewall tells you that an application has tried to connect to the Internet (and it’s not a program that you ran).
Your friends tell you that they have received e-mail messages from your address and you haven’t sent them anything.
Your computer ‘freezes’ frequently, or programs start running slowly.
You get lots of system error messages.
The operating system will not load when you start your computer.
You notice that files or folders have been deleted or changed.
You notice hard disk access (shown by one of the small flashing lights) when you’re not aware of any programs running.
Your web browser behaves erratically, e.g. you can’t close a browser window.
