I saw this screen shot last night on the WoW LJ community, and I have to admit, it took me by surprise. This is the first time I've ever actually seen the World of Warcraft launcher/load screen come out and point-blank warn people about the presence of Trojans on their machines. As there are a lot of variants of this particular Trojan out in the wild, that specific name doesn't surprise me.
Considering the fact that two Blue accounts were recently compromised, it looks like it's a good time to once again make sure your systems are patched, your virus scanners are up to date, and that you've got some good lines of defense against these Trojans. (Personally, I'm a huge fan of FireFox and some of the browser extensions that have come out for it.) Or, as some of my friends have told me, I could just get a Mac, and not have to worry so much about these kinds of things either. I keep telling them I'll happily switch when they buy me one.
