I have also gotten a page that claims to be microsoft support that locks up your system and tells you to call an 800 number.Just control-alt-delete and get out of the site. I have spoken to them about it and they said it is a scam. It has happened at least 5 times on CF.
It's likely that JavaScript (JS) is being used to power the site ads, and JS is known to have security flaws every now and then. I'm guessing they have a dirty ad trying to push some bad stuff.
If that's the case, it depends. They'd probably have to find the source of the JS exploit (i.e. identify exactly which ad is malicious) and remove it from their system by hand.Is that going to clear itself eventually...?
Thanks guys. I can assure you that the site does not have a virus. This is just reaction to some bad ads that get in the system.
Good news though. I spent an hour and a half on a conference call today and we are making significant changes to our ad system in the very near future. Going to really improve things around here.
