Lock out of Users on Windows XP due to braviax.exe virus

I received my brother in laws laptop (Toshiba Satellite) and installed AVG on it because it had no virus program and had a virus. The computer, on restart, then logged me out immediately upon choosing my user on XP. I then rebooted to Safe mode and was able to run a Command Parameters antivirus search from dos using avg 9.0. It found the braviax.exe virus and moved it to the virus vault. I then rebooted the computer and it immediately logs me out as soon as I log in. I then tried to reboot back into safe mode and it immediately does the same thing whether I use the Administrator or Owner username...Can anyone help me figure out what I can do? I thought about a total reinstall of the operating system, but the virus has somehow disabled my CDROM Multirom and taken it out of the equation....HELP please!

 

Welcome to MajorGeeks!

You may need to download and run a Rescue CD. If that doesn't work, do you have your Windows install CD?

Avira AntiVir Rescue System

1. Download the Avira AntiVir Rescue System
- If you need a free burning application, CDBurnerXP works on all operating systems from Microsoft Windows 2000 SP4 onwards.
2. Place a blank CD in your burner and double-click on the downloaded file.
3. The program will automatically burn the CD for you.
4. Place the burned CD into the affected computer and start the computer with the CD in the CD tray.
5. On the bottom left side of the screen there are 2 flags. Using your mouse click on the British flag to use English.
6. Click on the Configuration button.

- Select Scan all files
- Select Try to repair infected files and Rename files, if they cannot be removed
- Select Scan for dialers
- Select Scan for joke programs (Jokes)
- Select Scan for games
- Select Scan for spyware (SPR)

7. Click on Virus scanner
8. Click on Start scanner at the bottom of the screen.

9. Let Avira finish it's scan and then remove any threats found and then exit out of the scanner.
10. Take the CD out of the CD/DVD tray and then restart the computer.

If needed see this Tutorial for the Avira Rescue CD

 

The problem is...the virus has disabled the cd rom.

 

When you start in Safe Mode have you tried the 'Last Known Good Configuration' option?
