How to fix
“McAfee Security is not compatible when Windows 10 HVCI mode is enabled”
on Windows

Hello. I tried to open the McAfee app but I received the "McAfee Security is not compatible when Windows 10 HVCI mode is enabled" error message even though I am on Windows 11. What does it mean?

The "McAfee Security is not compatible when Windows 10 HVCI mode is enabled" error message indicates that the McAfee security software installed on your computer is not compatible with a security feature called "Hypervisor-enforced Code Integrity" (HVCI)[ref en-1] in Windows.

HVCI is a security feature that helps protect against malicious code injection attacks by enforcing code integrity at the hardware level. It does this by running the operating system and applications in a virtual environment and only allowing code to execute if it has been signed by a trusted source.

If HVCI is enabled and you are trying to run McAfee security software, you may receive the "McAfee Security is not compatible when Windows 10 HVCI mode is enabled" error message. This is because the McAfee software may not be able to function properly in the virtual environment created by HVCI.

There are also reports that the McAfee Security Scan Plus app might be the one to blame. It is a free version of the diagnostic tool that scans your computer for viruses, malware, and other security threats. However, if you already have another paid antivirus plan like McAfee LiveSave, the free app may cause interferences and produce errors.

When you download certain programs, such as Adobe, you may be asked if you want to add the McAfee Security Scan Plus app to your download. This is called software bundling. It is important to be cautious and not check the box to download this app, as it is separate from the McAfee LiveSave app.
