Anyone get a notice saying 'Windows Defender turned on' and 'McAfee incompatible'?

Hi.

I leave my computer on at night. I woke it this morning (Sunday 9-25-16) to find that my background is now the Win 10 default. There's a notice in Action Center that says,

"We've turned on Windows Defender. Your version of McAfee Anti-Virus and Anti-Spyware is incompatible with this version of Windows. Do you want to keep using Windows Defender, or update McAfee Ant-Virus?"

Has anyone ran into this? Is it something I should be concerned about?

We've had this version of McAfee Total Protection on for several months and no issues. Updates are current. It's my roommates and is for several computers. His computer hasn't got this notice so far.

Any help or advice is appreciated.

Thanks,

Heavy

Run the Virtual Technician to see if it finds and fixes anything, if not, look on that page slightly lower down on the left for "Contact Support" and contact Technical Support.

I ran Virtual Tech. It finished and said fixed as well as 'Update trusted Microsoft Certificates'. I guess that's what the update button with the original notice was for. I clicked that and did restart. So far, no notice returning and Win Def is off.

Thanks Peter M for the quick response. Much appreciated. Anything else pop up I'll hollar.

Take care,

Heavy

Also keep in mind that in (Windows 10) Windows Defender is not compatible with McAfee/or any Anti-Virus Application. As unlike any OS before it's introduction contains Anti-Virus capabilities. Hence running (2) RTS Modules will cause conflicts and clashes.

All the Best,

For moderators, FYI :

Cross-linking this thread to the other thread where a user encountered the "Update trusted Microsoft certificates" message when running MVT. So this may refer specifically to files used by McAfee that need to be updated? In both cases the OS is Windows 10 (build not known).

Please Run Quick Clean from Navigation and perform McAfee update.

Hi Heavyhauler,

Can I ask please whether this device upgraded from Windows 7 to Windows 10 some time between September 2015 and January 2016?

Regards,

Colin
