WScript.exe is Infected By Malware and Firefox Opens Harmful Websites

2013-05-20T05:52:00.001-07:00

Yesterday I witnessed a script based malware attack on my computer. I strongly believe the malware infected my computer came from one of my friend's USB drive. He double clicked a folder to open in his pen drive but it was a short cut created by a malware. The target location of the folder was the below address. C:\windows\system32\cmd.exe /c start WScript d3d3\icec.js & Start Explorer.exe "RECYCLER" and I believe WScript.exe is infected by this malware. This script automatically set the home page to "http:// india4you. info/r.asp#" in Firefox. Also the default Search too changed to one malicious URL address. Gladly Avast installed on my computer is able to detect it and stop Firefox from accessing the page.

Just like this, Avast web shield starts stopping a number of attempts to connect Firefox to other malicious websites and while carefully analyzing each attempts, it is found that the process is originated from WScript.exe

How to Resolve WScript.exe Infection

Since the first location we should check after malware infection is Startup, I tried to open System Configuration using msconfig. This script created some unwanted Startup services but Wscript.exe prevented me from opening msconfig on my computer. So the steps I took to fix this issue are provided below.

Open Task Manager and kill Wscript.exe under processes
Now type msconfig on Run and press OK
Uncheck all suspicious Startup programs under Startup tab
Reboot the computer and check whether Wscript.exe is still under processes. If it is still present, you need to repeat the process and disable all Startup programs except AntiVirus.

As we know most of the script based malicious codes prompt browsers to load other compromised websites for various reasons. If you discover such website, there are some steps you can do against it. To lean more about how to deal with infected websites follow the link below.
How to Deal With Malicious Websites and Stop Them From Spreading Malware

After the infection the major problem I was facing is the slow Internet because of the automatic attempts of Firefox to access remote compromised websites. Luckily Avast web shield protected my computer from opening those websites. To view the saved user names and passwords from Firefox follow the link below.

Importance and Advantages of Having Deep Links to Your Website

2013-04-18T06:00:00.000-07:00

One of the main questions many newbie webmasters ask in webmaster forums is if it is enough to create back links to just the home page? For a product or service website with one page, it is enough to build backlinks to just the home page but it is not enough for a big dynamic website. To get more targeted visitors to a big website, it is important to develop backlinks to the inner pages. Deep links refer the links pointing to the inner pages of a website other than the home page.If a webmaster is developing backlinks to just the home page and not to its inner pages, entire baclink structure looks suspicious and Google may detect it soon. It is because if all the backlinks are achieved by natural methods, they should be pointing to relevant inner page. Another reason to get deep links is potential inner pages will not get a chance to appear in Google Search results without having the support of back links because Google treats each web pages separately.

Advantages of Getting Deep Links

Looks more natural in Google's eye: It is true that most of the natural links developed over time are pointing to the inner pages of a website rather than the index page (home page).
Deep links helps inner pages rank high in Google Search results

2013-03-20T10:53:00.000-07:00

When we want to extend a wireless network beyond the range of current wireless network, we should use another device called Wireless Range Expander. To increase the range and accessibility of a wireless network from an access point or wireless router we need to add Wireless Range Expander (Wireless Repeater) in our network. Wireless Range Expander is a device which extends the wireless network range as its name mentions. Wireless Repeater/Expander is working by receiving signals from Wireless Access Point (Wireless Router) and repeat the same signal. Linksys is one of the reputed wireless Range Extender manufacturer. Two well known models WRE54G and RE100 are from Linksys family. This tutorial is an update of one of my old guide to install and configure Linksys WRE54G on a network. Now in this new update, we have included steps to setup Linksys Wireless N Range Extender/Bridge RE1000.

Setup Linksys Wireless N Range Extender RE1000 Manually

Manual configuration of Linksys Wireless N Range Expander RE1000 is:

Reasons to Assign Static IP On Computer While Configuring Range Expander

Since the completion of my previous tutorial, I received many queries asking the need of assigning static IP address on computer before configuring Range Expander. The reason is very simple, Range Expander does not have DHCP server to provide an IP address to the computer. So in order to login to the web based setup page of the device we need to assign a static IP address to the computer in the same IP address range. While configuring router we do not have this issue.

Difference Between Configuring Modem in Bridge Mode and PPPoE Mode

2013-02-18T10:45:00.000-08:00

As I mentioned in my old posts, I started my career in computer networking as a SOHO consultant. In first few months we were assigned to configure Local Networks in small offices. During the time first thing I learned was the differences between configuring a DSL modem in bridge mode and PPPoE mode. It is because the mode of modem configuration entirely affect the router configuration. If your modem is configured in bridge mode, you need a dialer to access Internet and every time you must enter the Username and Password provided by ISP. If your modem is in PPPoE mode, the connection is always on. It means you do not need to use any dialer to access Internet. Below you can see a summary of differences between modem in bridge mode and PPPoE mode.

Major Differences Between PPPoE Mode and Bridge Mode

Bridge Mode Supports only one computer but PPPoE supports multiple computers
In bridge mode you need to dial every time to connect Internet. PPPoE mode is always connected.
PPPoE is more secure compared to bridge mode.
In Bridge mode there is no need for port forwarding but in PPPoE mode you may need port forwarding
NAT is supported in PPPoE mode but in bridge mode there no no NAT
computer connected to modem in bridge mode gets the public IP address but in PPPoE mode your computers get private IP addresses.

The most important difference between PPPoE mode and bridge mode is the number of computers supported in each mode.Only one computer can be connected to a modem configured in bridge mode. Since NAT is supported in PPPoE mode, we can connect multiple computers to a modem in PPPoE mode. Computers connected to the modem in PPPoE mode can access Internet directly because ISP username and password are saved in the modem. Computer connected to a modem setup in bridge mode need you to login with username and password provided by ISP and dial to access Internet every time. Modem in PPPoE mode can work as a router with feature like NAT, Firewall, DHCP etc. With these additional features modem in PPPoE mode is more secure than modem in bridge mode. You may need to perform port forwarding on modem configured in PPPoE mode for the proper working of certain applications. You do not need to do port forwarding on modems in bridge mode.

As per the above post, we can see it is better configure your modem in PPPoE mode unless you have other priorities. In case if you want to learn a practical example to configure a DSL modem in PPPoE mode, click on the link below. How to Configure Reliance DSL Modem in PPPoE Mode
