VirusRemover2008 Removal Guide (Uninstall Instructions)
Hi, I've recently been infected by the VirusRemover2008 rogue anti-virus program on my Windows XP. I've bought SpySweeper and PC Tools Spyware Doctor to try and get rid of this problem. The SpySweeper found nothing, but the Doctor program found the VR2008 files and deleted them, or so I thought.
I still get the popups and I've tried following guides to removing the DLL files, processes, and registry entries. I was able to end the process in the Windows Task Manager, but there is still no end to the popups. I tried finding the DLL files and entries, but I can't find ANY of them.
I've looked for other forums and posts over anyone else that may have had this problem, but I've seen none. I've tried McAfee scans and system restore (the restore doesn't finish for some reason). Been very annoying.
Any help would be greatly appreciated.
