Hello ?

 

Welcome to the Webropot Community,

 

Windows will not allow two antivirues to run. That's just the way Windows is. If you don't have an AV then Windows will enable Windows Defender.

EDITED:

If you have another AV such WD installed on Windows 8, 10, it will automatically disable Windows Defender.  It will not allow you to have both enabled at the same time.  This is a function of Windows, not Webroot.

 

If you uninstall Webroot (or other AV you have installed) Windows Defender will automatically come back active if it was set for that, OR it will provide you a system notification that action is needed in order to either turn Windows Defender back on or re-enable/re-install your other AV.

 

IMO you really only need Webroot...

 

Please have a look here if you want to run them both. Please be careful when changing the registry.
