First off, I need to say that my computer isn't infected with a virus, but I'm not sure where to post this question at.

I have acquired a virus file that keeps trying to install the Vundo virus on my computer. I have the Bullguard software running and Bullguard keeps blocking the file from installing on my computer. Every 5 minutes or so, Bullguard will give me a pop-up saying that it blocked the Vundo virus from installing; it also gives the infected file name. I am able to use Bullguard to scan the file and delete it successfully. But, no matter what I do, the file always comes back.

These are some of the options I've already tried:
  • Turning off System Restore
  • Deleting the file in Safe Mode
  • Using a shell command program to delete the file before Windows starts
Here is the name and location of the file, and it's actually 2 different files:

c:\windows\system32\TEeLRXbc.ini
c:\windows\system32\TEeLRXbc.ini2

Unfortunately you are already infected, bullguard is just trying to keep the infection from growing?

Looks like vundo was installed rather well, make sure you reboot and run another quick scan

I deleted everything and rebooted to make sure all the delete on reboot files were taken care of. After I rebooted, some of the files were already back.

So, I rebooted into safe mode and ran the scan again and deleted everything again. After doing a regular reboot, none of the files returned, and MBAM didn't pick up anything, so I think I'm clean.

I was definitely infected, but thanks to Bullguard, the infection didn't get out of hand. I've had Vundo do a number on another computer before, and that hard drive was unfixable.

Thanks for the help.

Ok you look clean,nice work.

Now you should Set a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since System Restore is a protected directory, your tools can not access it to delete these bad files which sometimes can reinfect your system. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Then go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
