Not head of this one before. Friend phoned to say he had had a couple of phone calls from someone claims to be a MS accredited body, saying he had a polymorphic virus and they could talk them through the removal on the phone. Friend is savvy enough to tell them where to to go, but phoned me to check, googled a couple of bits of info he gave me and hit a couple of other reports of the same thing (but only a couple - so it might be quite a new idea). I suspect they are trying to get you to download something or allow them to remote desktop to your machine. Anyone heard of this sort of scam before?
