The support agents seem to run all commands, why is it not available on support websites for a guide to completely remove it and just always redirect for filing a ticket.

Yes, Webroot does have Sudo Commands to completely remove Webroot from the Mac Computer. I don't know though if the sudo commands change for every Mac version. I don't want to give you the wrong information. It's best to submit a Support Ticket and they will send you the right sudo commands for your Mac. Make sure to tell them what version macOS you're running.

Support Ticket System is Open 24/7
Note: When submitting a Support Ticket, Please wait for a response from Support. Putting in another Support Ticket on this problem before Support responses will put your first Support Ticket at the end of the queue.
