After installing Webroot Secure Anywhere, I noticed that Windows Defender continued to run and appears as the primary security software under Windows Security - Virus & Threat Protection. This is not the case when using other security software - examples that come to mind are Norton 360 and Sophos.
Also, the Windows Antimalware Service Executable is running all the time, performing scans and using significant resources. While I tried turning it off, including through the Windows Registry, it cannot be disabled.
I’m pretty sure that this is a defect in the Webroot software, unless Webroot has decided to use the Windows antimalware engine in place of its own. Note that I have tried this on two different machines running Windows 10 and Windows 11 respectively with the same result. And aside from Windows Defender, which Webroot should be disabling, there’s no other security software running.
I’ve opened a Support Ticket with Webroot Support, but have heard nothing yet, so I was hoping to get some answers here.
In the meantime, I’ve removed Webroot and installed Norton 360 to reduce resource usage, which was over the top with both Defender and Webroot running.
