Hiya dagul,
Well, you could try system restore, But, that would mean losing all the data since that time.
Anyway, now that you have AVS installed, Panda is not really necessary. If you want an online scan for a second opinion, both BitDefender and F-Secure are the equal, if not better, than Panda.
I scan with AVS, SUPERAntiSpyware, AVG Anti-Spyware (formerly ewido), GMER, and gmer's catchme.exe regularly. I sometimes scan with Ad-Aware SE and/or Spybot-S&D. I hardly use the online scanners unless I'm bored or something.
