I am working on a machine that had spybot s&d. The program has been know to cause machines to slow down terribly, and so I removed it. Upon restarting the computer, it now comes to a stop error. As it worked previous to the removal of spybot, I know that is the problem. So now I am trying to get into safe mode to get the computer set to an earlier date. But attempting to get to safe mode is doing a stop error also. What do I need to do?
