Teamviewer may also connect via http/https to their (proxy) servers.  In addition to blocking TCP port 9538 in general, we have  added "teamviewer.com" (no wildcards, it captures second-level domains as well) to a custom web rating override category (i.e. "blacklist"), which is blocked in the web filter profile (using certificate inspection only). This should improve the detection/blocking in general.

MrSinners

While this is very trivial, ensure that the correct firewall policies apply the AC and or web-filtering profiles.

The solution has been given, please read the other comments.

The last one from Mr. Sinners is important but sometimes forgotten, make sure you apply the application control to the right policy in order to work :) Goodluck.
