Just a heads up... quote from a blog post over at Kaspersky Labs: "Over the last few days, we received numerous reports of computers infected with fake anti-virus (scareware). The name of this particular culprit is Antivirus 8." "The interesting thing about these cases is that the users were getting fake anti-virus browser pop ups while not actively using the computer. During our research we noticed that these pop-ups would appear right when ICQ was fetching/displaying new ads." You can find other fakes to watch out for here at Superantispyware blog.
