I'm not exactly sure how, but my computer is, or appears to be, infected with Trojan Vundo.CO/CN/CI/CM/CQ/CR according to the AVG Anti-Virus Free program I use. I suspect it started a couple days ago when I was browsing google looking for general PSP info and a popup stating facts about Spyware came up on a site. Since then it has appeared multiple times, popup sites advertising spyware removal have plagued my FireFox browser and IE. Most of these symptoms have died after running AVG, Spybot S&D and Combofix (which deleted multiple files/infections). But AVG is repeatedly telling me I have the Vundo.CO infection in my System Volume Information folder/ system32/svchost.exe or something of the like. I have ran Combofix and Vundofix and the monster still persists.
