I just got hit by a Malware attach when I browsed to this site. I'm pretty sure it was from one of the ActiveBoard banner ads.
This warning applies in general not just if it happens here.
If a window pops up offering to scan your PC for free saying you have a virus this is in fact a malware attack about to happen on your PC.
No matter what you do. Click ok, cancel, click the little box in the corner, or even press Alt-F4 it takes it as a positive response and starts installing crap on your PC
The only solution is to Ctrl-Alt-Del and use Taskmanager to kill your browser. Also some browsers if killed, like firefox, may automatically reload the last page viewed so restart your browser with the internet unplugged to be sure.
I know a lot of you already know this kind of info but for those of you who don't I thought I would share.
BTW I contacted ActiveBoard about this. I don't know if they will do anything
