PowerShell script to forcefully remove Webroot SecureAnywhere. It is recommended to run the script twice, with a reboot after the first run.

Thank you for sharing your experience @DomingoMontoya @kzieres61 @xAndyxNL

02/22/2024: Successfully ran this script remotely (from a local server to a W10-64 domain member) via a psexec window started as SYSTEM (psexec -s \remote_workstation_name cmd), then invoked powershell in the psexec window and ran the script. Following reboot, all WebRoot services and folders were gone from the workstation. This will be a time saver.

Thanks for the script. Though it does get rid of some of Webroot, it has been obsoleted by Webroot, unfortunately.

This link on the webroot site has links to two small removal utilities you can download and run to get rid of Webroot for good. This is the best/fastest solution.

The first is called CleanWDF.exe. Run it.
The second is called WRUpgradeTool.exe. Run it. Don't worry, it is a removal tool, and won't upgrade/install anything. I don't know why it is misnamed so.
