I use Firefox as my main browser and twice today while logging into my Adsense account Windows Defender found a severe threat level virus called: Backdoor:Win32/IRCbot.dl. To verify I switched browsers to I.E. Again, as I was at the login page I got hit with a warning telling me an application on the page wanted to open Adobe Flash Player. I closed the dialogue box; login and the Flash Player wants to install again.
Anyone Else? I've done a full system scan on my system and that was the only virus detected.
