I just cleaned a copy of this beast out of my cousin's machine a few weeks ago. This thing does a pretty respectable job of locking down your system when you start trying to remove it. Half of the start menu gets disabled. No 'Run,' no 'Search' no access to root drives. 'Your system administrator has disabled task manager.' No problem, right? Just boot up in safe mode. But then I find there is some low level process killing explorer.exe every six seconds. In the end, I had to to mount the drive as a secondary on a different machine and scan it from there.
It does look pretty convincing. I can see where an average windows user would fall for it... maybe even a slightly above-average one. I had to laugh, though, when it kept telling me about these incoming hack attempts while it was off the network.
