Mcafee Safe connect wont allow me to unistall

Hey NSF. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

I would uninstall any 3rd party antivirus and try running only built-in Defender which gives adequate protection, best Windows performance, least issues, and is from Microsoft who knows how to protect their OS best.

If McAfee won't uninstall normally in Settings > Apps > Apps & Features, then use the special uninstall tool: http://service.mcafee.com/FAQDocument.aspx?id=T...

Run full scans with the most powerful on-demand free scanners Malwarebytes and AdwCleaner:

Clean up anything they find, restart PC and then run both scans again until they come up clean.

Then check for damaged System Files: https://www.lifewire.com/how-to-use-sfc-scannow...
If it cannot repair them see Step 10 here to continue: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Please run MCPR:
