Hello my name is Ben and my computer (Vista) has been infected with serial99. I have read several threads by others with the same problem and followed the advice given there. This includes following the instructions on the "Viruses/Spyware/Malware, preliminary removal instructions" thread, running complete scans with SS&D, Ad-Aware 2007, SuperAnti-Spyware, HijackThis and my anti-virus Trend Micro PC-cillin, and searching for various programs on the Add/Remove list. This has removed some of the malware but I still cannot run some programs as system administrator. This is the only remaining symptom that I can identify. Any help would be greatly appreciated. Thankyou, Ben.
