It also happened on my work computer on Monday and my home computer last Thursday. I remember because I was up until 2 am trying to delete it. This is also why I haven't come to the site all week.
3. General description of the ads appearing on the page when the attacks occurred? Are screen shot or firebug captures available?
I don't have this. But the program is Antivirus 2010. There are ways to get it off your computer, but they require extra downloads.
4. What specific section/zone of the site where the users visiting when they saw the problems?
Forums. Opening in a new tab a forum thread. The page will load and then keep loading. I find that if you close Firefox, it stops the malware from downloading on to your PC.
