This isn't real virus that might to do some damage to computer.
This is famous hacker's tactic to force you to pay few bux for unneeded software.
They forcing you to visit some website and download some repairing software.
That software will display to you that you have million viruses.
Then it'll say that for cure viruses you need full version and it costs for example 10 bux.
Then you pay and get "full version", that do nothing but say that it cured all viruses on your computer.
Thats all.
They're got your money, and you didn't really had any viruses
