One course of action which may help...
1. Do a system restore to a point prior to the virus activating.
2. Restart and make sure it is not active anymore.
3. Do a complete virus scan.
4. Turn off system restore. This will/should get rid of any files that are held in the recovery DB.
5. Restart.
6. Turn system restore back on.
Most of the new viruses disable System Restore. Also Windows Update. Also your virus scanner. Also access to antivirus websites.
For those of you not yet infected I recommend doing a backup of System State. This is equivalent to setting a System Restore point, but it can’t be disabled.
