My computer (&McAfee) were working just fine. Now every time I log on I get an 'error' about Windows Defender. It come up with an "0x800106ba"  message. I says something like - a program disabled Windows Defender, restart or go to help and support. I've logged off & logged back on but the same message comes up. I've tried to go to help & support but didn't get anywhere with that either.

Does anyone have a solution as to how I can get Windows Defender back up and running?

Thanks
