Hello Mokshaji,

I need to know exactly what virus you have, and its location. Did your anti-virus program quarentine it? What problems are you seeing on your computer?

Let's start by running some scans and seeing what they come up with. :thumbsup: They should take out some of the malware.

***************************************************

Please download, update and run (one at a time of course!)
Spybot 1.3 and Adaware SE

Fix whatever they suggest.

***************************************************

If you need help running these tools, here are some helpful tutorials.
Spybot 1.3 Tutorial
Adaware SE Tutorial


***************************************************

Be sure to run Adaware SE with a Full Scan in the Safe Mode.

How to Reboot into Safe Mode
tap F8 key during reboot, until the boot menu appears...use the arrow keys to choose "Safe Mode" from the menu......,then press the "Enter" key.


The following explains how to set Ad-aware's settings to perform a "Full Scan."

In Ad-aware click the Gear to go to the Settings area.

The following items should be on a green check, not on a red X.

Under the Scanning button:
Scan within archives
Under Memory & Registry, Check EVERYTHING
In Check Drives & Folders, make sure all of your hard drives are selected

Under the Advanced button, check ALL under Log detail level.

Under the Tweak button...

Some of these may not be an available option, depending on your version of Ad-aware and your version of Windows. Do not be concerned if you cannot select a certain item.

In Scanning Engine:
Unload recognized processes during scanning
Include info about ignored objects in logfile, if detected in scan
Include basic Ad-aware settings in logfile
Include additional Ad-aware settings in logfile
Include used command line parameters in logfile

In Cleaning Engine:
XP/2000: Allow unloading explorer to unload shell extensions prior to deletion
Let Windows remove files in use at next reboot
UNCHECK: Automatically try to unregister objects prior to deletion

Click Proceed to save these settings. When you would like to perform a "Full Scan," switch the scan mode from SmartScan to Custom.


***************************************************


Please download, update and run the free A2 (A squared) anti-trojan

Let it fix whatever it wants to.

***************************************************


I know you may have anti-virus software, but sometimes its definitions are corrupted due to malware. Online scans are the best resort in this case.
Run this pc through the Panda Scan Online virus scanner
or Trend Micro Housecall Online virus scanner


***************************************************

You left off the top section of your Hijackthis log. Be sure to give me the entire log, as it is vital to analysis.

Next, reboot and post a fresh HijackThis log to this thread.
