It's all coming back to me now, it was sometime during spring 2008, when I got a ragdoll masters serial key from this website. I opened the .zip or .rar file (it's been over a year, so it's hard to remember,) ran the executable, then a folder called blackbird and a couple other folders appeared on my desktop and my background changed into a YOUR COMPUTER MAY BE INFECTED WITH SPYWARE background, and then Defender Pro went insane and detected 69 viruses or other types of malware, my parents and me had to do a system restore, nowadays, I learned my lesson about computer safety.

Keep the f**k away, does NOT contain any crack, serial or keygen. I downloaded a F.E.A.R. 2 "keygen" that was actually an self-extracting archive. It had 2 "readme.exe" and one "readme.bat" in it. After the extraction Kaspersky just went psycho: 4 registry deletion attempts per second, it was for Internet Explorer's addons or something like that. Plus any program I opened (even explorer.exe) tried to do that too. I tried to do the system restore thing, but it had an error and it didn't work. I opened Vista in savemode whit Command Prompt and guess what, it (cmd.exe) crashed. I eventually restored Windows the next day.
