After a user complained of popup windows advising her to download antivirus software, I checked the system with Spybot Search & Destroy. Spybot found the following malware on the system:
FunWeb
FunWebProducts
MyWay.MyWebSearch
MyWebSearch
TagASaurus
Zlob.VideoAccessActiveXObject
I also found that the popup ad was appearing whenever Internet Explorer was opened. When Interenet Explorer was opened it would go immediately to http://aprotectservice.com/, which would result in a dubious W32.Myzor.FK@yf virus warning appearing.
