There is a Russian scam that is well known - if you accidentally load one of those programs that is supposed to clean or speed up your computer it actually infects it. That message to pay $60 to get rid of it - when you call you apparently get a Russian accented voice on the other end who takes your credit card information and gives you information for how to remove or disable the virus. If you use Malwarebytes, and if you search of the infection at BleepingComputer.com, you can get rid of it yourself. I've talked a couple of friends through the steps long-distance.
