If You’re Paranoid, Remove TeamViewer

So, naturally, this is in response to the recent allegations that TeamViewer has been hacked…

While TeamViewer hasn’t admitted to having been breached, and although what they’ve suggested is completely plausible, one thing is clear: What has been reported thus far doesn’t give me the warm and fuzzy … so I’m going to play it safe for now.

I put together a script to remove TeamViewer from not only ma own machines, but also from the machines of friends and family I often support.  I’ve run this on Windows 7+ and so far it works as expected.  If you run into an issue, let me know and I’ll do what I can to troubleshoot asap.


  1. If you’re not using a password manager or are still using easy to remember passwords or are recycling/reusing passwords across multiple sites;
  2. If you’re not using two-factor authentication (2FA)

You really should reconsider.  Check yourself out on https://haveibeenpwned.com/ to see what accounts may have been compromised in a data breach and take the necessary precautions.

This needs to be run from an elevated PowerShell console or ISE.
