I believe my teamviewer account has been hacked and I can't sign in with my old password and the emails I'm receiving to reset it seem bogus--scamming. How do I delete my TeamViewer account and start over?
Without access to the Management Website, you will need to contact suppport. It may just be easier to start with another email address. If this has been an issue once, you are going to want to figure out how they got your password. You may want to consider setting up two factor authentication as well.
As a follow up thought, I would also suggest going to each of the machines you have a host or TeamViewer installed on and change their passwords.
