About two weeks ago there was a major update from McAfee .. the next day my pc kept locking up, I couldn't do anything with it. So I had to open in Safe Mode and restore registry to a previous date before the McAfee update.
That got my pc working again. Unfortunately, ever since then my NPPlus flashes up every 30 minutes or so, saying either that my Computer & Files are not protected and/or my Internet & Network is unprotected. I press Fix and the problem goes away.. but temporarily.
If anyone could advise me, that would be most appreciated.
I suggest turning off the McAfee software temporarily while performing the troubleshooting steps in the article. If it resolves the issue with Defender, you should then be able to turn off Defender and use McAfee with no issues.
