MSP here. I’ve seen other posts that discuss Webroot with Windows Defender, but now that it’s 2021, Windows 10 has changed a bit.
Why other posts don’t apply anymore:
- Disable periodic scans in Windows Defender is no longer an option
- According to this article, you can set a DWORD value in the registry to enable Passive Mode for Defender, however, upon setting it, is has no effect on issue #1 below
- With Webroot + Windows Defender enabled, Windows Defender is still actively scanning data in real-time. I ran a test and saw the Microsoft Anti-Malware service spike up to 30-40% CPU usage. Webroot is installed and functioning correctly, but Webroot doesn’t seem tell Windows Defender to turn off. I have a registry hack to force Windows Defender off, but I’d rather not apply that unless I have to.
- In addition, if I disable “Real-time Protection” in Windows Defender, I get a toast message that says that Windows Defender & Webroot are both disabled, even though Webroot is actually enabled.
My clients are asking why they are paying for Webroot if Windows Defender is doing a ton of work behind the scenes anyway….
