These things have been floating around the internet since at least June 2008 and they still get past almost every antivirus software if you use internet explorer.  I found a list of all the known names so far so thought I would post... might just save someone some headache if they know all the different names this crap goes by... knowing is half the battle :P

Malwarebytes' Anti-Malware tends to get rid of most of these in my experience but I make no promises. http://malwarebytes.org

It doesn't work that way!* These are scams, they present to users a false promise/premise, and con the user into clicking and executing a bogus program, bypassing all protections. It does this because the computer user tells the non-thinking PC to do so and, like an obedient and dumb servant, the PC does exactly what it is told to do. That's how PCs work![/quote:c4fd75148b]
