I had a problem a while back where automatic scans weren't starting when they should. I eventually re-installed McAfee (following the instructions), and using the MCPR, and ran the MVT.
It tells me that real-time scanning isn't working (even though everything is 'green' when I open McAfee), so I run the fix and it tells me it will run an update. I need to wait 10 minutes and then run MVT again to check it's worked.
However, I get the same error message. Real time scanning not working. I have run the MVT 6 times now. I've re-booted.
Plus automatic scans still aren't working. The time just gets moved forward 10 minutes or so each time (it's just moved it forward an hour) it's due to start the scheduled scan. When I did the re-install, I remembered to uncheck the box under General Settings, so it shouldn't wait until my PC is idle before starting the scan.
Now I know that I can run a scan myself (which is what I have been doing), but I need to have confidence in McAfee. So when it all looks OK but the MVT tells me it isn't, what am I to think?
My PC runs on Windows 7, IE11.
