My mother's Thinkpad is having some problems. If you try to open My Computer, the Control Panel, Internet Explorer, etc., the desktop and taskbar will disappear for a second, then when it comes back, the cursor will be an hourglass for a second, and then nothing will happen.
I've scanned with McAfee, found a couple of trojans and removed them, and I scanned with Spybot and removed a few things. I've tried reinstalling Internet Explorer, and the installation progresses to 87% and stops. I've run our of ideas at this point, any help would be appreciated.
