McAfee protected my computer from it so it only locked a single window of IE, so I just went to ‘processes’ window and killed the IE session which closed all those windows.
This happened a few times but never resulted in a problem.
So far McAfee has done its job.
Are you saying that some problem shows up when you boot up your computer?
Yes; as soon as I booted up the computer, there it was. So of course it won’t let get to Start, another window, etc.
