If it's not one thing, it's another. Come on!
I'm currently running Windows Defender, Ad-Adware, Spybot, AVG and Panda ActiveScan which is the only one to have found anything so far. I got suspicious when I got a strange error message on start up about winlogon and seeing an exe by that name running in the task manager. I could not find any definitive answer if is it's a virus / spyware or just a normal windows process.
There went my night.
Update: After leaving my system to get scanned over night I still don't know if I have / had a virus or not. The viruses Panda found we false positives and Windows Defender came up empty. And all Ad-Adware and Spybot found were tracking cookies. The downside is this doesn't rule out that I don't have a virus.
