My PC was infected with the same malware problem as outlined by MLinau (Google Gala Hijack - http://www.bleepingcomputer.com/forums/topic259577.html)
. I followed the steps recommended to her ... all except for the last one, which turns out to be a pretty important step. I did not click Start >> Run and type in ComboFix /u. After ensuring the malware was gone, I rebooted and the PC came up with the Windows User Account screen which I have never used before. It asked me for the password to login under the user account for my last name but since I didn't know the password (doesn't exist to my knowledge), I logged in as guest. It proceeded to tell me there were several files missing and brought up a half-baked version of Windows. I tried to run the ComboFix /u command but it tells me I don't have access.
Any ideas on how I can undo the ComboFix now? I appreciate it. Your help was huge until I shot myself in the foot.
