Please follow the the instructions for using Vundofix in BC's self-help tutorial: "How To Remove Vundo/Winfixer Infection".

After running VundoFix, a text file named vundofix.txt will have automatically been saved to the root of the system drive, usually at C:\vundofix.txt. Please copy & paste the contents of that text file into your next reply.

If there are no more problems or signs of infection, you should Create 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 this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. 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.
  • 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.
