My computer keeps rebooting itself! I can't even log onto it! The only way to get on it is in safe mode. I have recently installed a program and after that is when it started doing this. I tried to unistall the program in safe mode, but it wouldn't let me. The program happens to be norton 2007. I have heard that this is a possible worm. Can anyone help me? any thoughts on what I should do? Right now, I am using my husband's mac, its an older mac. thanks in advance.
