I, without a doubt, beleive there is a terminally malicious AD on there. I got this fake warning twice about “Viruses were found on your computer.” Note this warning is fake. So be careful.
I don’t know which ad it is on DA but it acts like a pop-up inside the tab. Whatever you do: DO NOT CLICK ANYTHING IN THAT TAB EXCEPT TO CLOSE AND LEAVE THE PAGE. As fun as DA is, I suggest not going on it for a while.
If you’re in doubt, I sugest doing your personal FULL-scan (include the rookit scan) from your own antivirus software and maybe try to get an ad-blocker (most schools and companies have them, they don’t let any ads show.) Not sure how effective an Ad-blocker will be but blocking pop-ups won’t work on it considering I block pop-ups and it still came up.
(If you’re not sure what sort of antivirus protector you need to buy for your computer, Kaspersky is the current for 2012 here. There are more though for 2012, but any “claim: they’re the best.)
It’s no secret that DA has had this problem before, they still do and they can’t trace where it’s from because of incompleted submissions and inability to find the trace of that ad or where it came from. Not even I know where it’s coming from. I’m very shifty about DA at the moment and I’m steering clear of it for now.
Just a warning guys. I got this fake warning three times now, be REALLY careful on DA now. I have tried to submit a form but I need further evidence, such as a REALLY helpful screencap for them. I am also having trouble knowing where to put this form.
