My desktop has disappeared into a black hole, something called Security Tool Firewall pops up every two seconds asking me if I really want to continue unprotected (and wants to charge me a buttload of money if I don't), apparently everything from my toolbars to my files is infected with lsas.blaster.keyloger, and I can't make my baby's Parry Gripp playlist play on Media Player. <----- Now this is truly an emergency.
I googled the whatever cannot execute failed whatever message that comes up when I try to play Media Player and found some free Windows 7 scanner thing, but according to Security Tool, IT is infected with keyloger and when I try to download and run it, it just disappears to some unknown place.
I don't know what to do, I'm just an average person with a basic knowledge of computer stuff, I know how to use it and that's it.
Can somebody please help!!!
