just removing the content of my main post for a few reasons i wont list. Pirox remains to be the only infections on my computer and I'm on my second set of scans with new software. Nonetheless, pirox is still the likely candidate.
edit:
additionally, I download next to nothing, i dont use addons, i dont download anything wow related and the only wow related websites i go to is warcraftmovies.com, even then, i only stream. Unless warcraftmovies.com has been known to sneak keyloggers into your computer through advertising (and no, i dont click on the ad's), I don't see another possibility.
