Yeh that sounds like a virus...get a friend to give you Google Chrome on a flashdrive or something so then you can access the internet and download Avast! Free antivirus. Just stay calm and don't do what it says
Or, it could just be that an evil friend is trolling you..
Yea
Try getting Avast and Super anti spy ware, i am using both of these right now and they are both great for removing viruses but there are special guides for removing this virus
It's not called anything, various vendors have their own rescue products.
Suggesting just one product for anti-virus recovery isn't wise; as (a) it may not resolve the problem, and (b) especially as we have no idea what specific infection they have.
