Just ran a scan with AVG free. Found a virus/worm named small. It infected the c:\windows\system32\_.vbs and c:\windows\system32\_.bat AVG could not heal it so I moved it to the virus vault. Next scan its found again.
So far windows is working normally except I cant double click the c: icon in control panel.

ANy cure or do I have to reformat? Hope I dont need to reformat cause I have tons of data to backup.
