I got a good one (well, one of the computers from work does anyway). WinXP Pro SP3, laptop boots straight into a fake virus scan and starts "finding" viruses on it. It hides the start menu, no right-clicking on anything, the task manager is greyed out when you ctrl-alt-del. Even booting in safe mode w/ command prompt, you can't run regedit. I think this one got me. Anyone ever successfully beat one of these suckers without having to reinstall the OS? Wanna kill these ads? We can help!
