I've been seeing a lot of this lately. A lot of my clients are getting it. No one knew how to get rid of it when it first came out, but aside from the links posted above (I haven't tried any of them),
Malwarebytes is the only thing that can *easily* get rid of this trojan. Everyone's virus scanner is missing it because it's not
technically a virus - it's malware. People think it's something they need or that it's legit, so they click on it... The best I can do is advise people to use firefox and not to open emails from sources they don't know, but even then, it's difficult to train people (especially OLDER people) to identify false popups. I can smell the bull**** in a split second, but a lot of people just click away happily and let the trojan in.
One guy got it from an actual fedex email, so caution there. It is advisable to install Linux or get an Apple ASAP - You'll never have problems like this again :-P. For now install Firefox and Thunderbird.
I get paid to deal with things like this, and as much as I like making easy money running Malwarebytes and virus scans, the world is a lot better off avoiding these problems to begin with.
