Has anyone experienced any problems with adware or viruses while browsing or using deviantart? So far, my computer has only had 2 infestations since I built it last year, and both happened while using deviantART, although I was using other websites at the time, so I'm not one hundred percent sure as to what the source was.

At the time I was using Internet Explorer, but now I have switched to Firefox, and I have set up another firewall from Zone Alarm, in addition to McAfee, so hopefully none of that foolishness will happen again.
