Yes, my mother got this twice on her computer, and she freaked out! After a few hours and following instructions on Major Geeks on how to get malware off the computer, I fixed it for her. Viruses can come from the most unlikely web sites. One time I was looking up vaccination time tables and our computer got infected. But never, never, never click on a pop up box that says your computer is infected and they have software for you - it's a virus. Yes, mom got one from that too.
