It's too late right now, I may have to do it tomorrow.

I made a stupid mistake about a year or so ago when I bought StopScan antivirus. I think I was looking for AVG, clicked on the wrong link and ended up buying this thing.

I also have free AVAST but I don't know if these two like each other and if it's doing anything except for showing 'virus database has been updated' message every time I open IE or Outlook.

I had some antispyware but haven't tried to run them for a while now...
