McAfee internet security through Shaw is installed on all my computers. I have turned off scheduled scanning as I prefer to run my scans manually when I choose. But McAfee seems to decide to run a scan whenever it wants without any notification or warning (or reason). I'll just notice a computer is running slowly and if I open McAfee it is running a scan. If I try to cancel the scan it takes several minutes, or just ignores the request and continues merrily scanning away. And no, automatic and scheduled scanning are turned off. Is there some way to stop McAfee from doing this???
