I have Norton (2006?) and its doing fine. Actually, it expires in like 4 or 5 days so Im screwed after that.
Its a lot better than a lot of the others I have used. I don't get anything popping up, the one problem I have is that it doesn't run the scan everyday like it should.
I just leave my computer on overnight sometimes with the scan running.
Ha! Irony, I just got a pop-up saying it expires in 4 days, awkward moment.
