I am trying this against a number of machines we have rouge Webroot installs on. I did need to make one correction because of an error. On line 51, "$Env:ProgramData\Microsoft\Windows\Start Menu\Programs\OpenText™ Core Endpoint Protection",. The TM after OpenText throws a powershell error. Some unsupported character. Once I removed that, it ran properly. Waiting for the user to reboot and we will see if it works!

@chadmark thanks for the info. For some reason on my computer, it has the TM symbol. I made some major revisions and added support for both, just in case.
