A few days ago I received a Google redirect virus which quickly progressed to a rootkit/trojan agent. AVG warned me of the infection and offered to prevent it, but I happened to be clicking on a webpage when the warning popup appeared and I inadvertently dismissed the warning. Immediately Google results started misbehaving. I probably should have done a System Restore or run my scan programs, but instead I followed another website's advice to download ComboFix and Frontline Cleaner. Mid-scan my computer shut down, and it was unable to restart.
Vista has run System Repair several times, but it has been unable to correct the problems it found. Using a recovery CD has not been helpful. My computer will only start in normal mode occasionally, and Safe Mode overheats, requiring constant cooling.
The virus had turned off System Restore, effectively deleting any restore points. I tried restarting System Restore by opening the System control panel and selecting System Protection, but the System Protection tab was missing from the resulting window.
AVG's Safe Mode Console Scanner is unable to complete a scan due to overheating, even with cooled air running through the laptop. WinPatrol continually informed me of system changes, all of which I denied. Malwarebit's AntiMalware located and deleted 16 trojans, and WinPatrol has been pretty quiet since then, but my laptop still won't restart properly and the browser redirects and popups persist.
After two days of trying to run virus scans and System Repair with no improvement, I found "Use last known good configuration." (This option is in the Safe Mode menu which comes up when you press F8 at system boot.) System Restore and System Protection are now back, but the restore points I lost are gone.
I've now run scans for AVG, Malwarebits, and Windows Defender, and all have come up negative. The laptop still overheats in Safe Mode, it restarts when put to sleep, and the browser redirects and popups remain.
