Don't get me wrong, I swear by AdAware, Spybot S&D, and CWShredder. But that was just weird.
I mean, WTF kind of thing could make removing it cause Windows to log a user off when it's removed? I've been in this game for about 10 years, and have never heard of any sheeit like this.
I told the poor b@st@rd to use another PC to make a boot disk, run it, and run the System Restore from the command line. Any thoguhts?
He probably had something seriously wrong with his computer before he cleaned it out. Tell him to reboot into safe mode (press f8 repeatedly during a restart). In save mode, go to start, run, and type msconfig. Go to the startup tab and disable everything listed there (except his mouse/keyboard, etc if listed). Then I would recommend he do a defragment. Start, programs, accessories, system tools, defrag. And finally, schedule the system to do a checkdisk at next reboot. He needs to open up explorer and find his C:\ drive. Right click it, choose properties, then tools, and checkdisk. Once he selects checkdisk, have him reboot and let it do its thing. It can take over an hour on a seriously damaged disk but it should fix the bad sectors on his hard drive. After that, tell him to boot into safe mode and run a full virus scan, then defrag one more time. See if that helps.
