I downloaded Spybot S&D and ran my first scan on an old pc running Windows XP. Needless to say when the scan completed I had a whole host of problems that needed fixing - I believe it said fixed 284 problems and 6 couldn't be fixed. It said my computer needed to be restarted and asked if it could rescan upon restart to complete the fixes. When my computer restarted I got a black box that normally flashes through on start up, but didn't go away, then I got another and another and the boxes just kept appearing. I finally opened the task manager and get them all to close and shut down and haven't rebooted since. What was all that?
