Firewall blocks Taskmgr.exe
« on: September 24, 2022, 04:45:44 PM »
A week ago, I assembled a new PC (AMD R9 5900X) and installed Windows 11 (21H2) on it.

I have used the free Comodo Firewall in the past and have appreciated it, so I went to Comodo's website and only found CIS, which I downloaded. It contained much more that what I wanted so I uninstalled it. Looked around some more and finally found a link for the free Comodo Firewall ( on Comodo's site and downloaded that. Everything seems to be running well except for HIPS. Every time that I start Taskmgr it then appears in the Unblock Applications window. I have unblocked it there numerous times and it always shows back up. 

Next I tried the  Advanced Settings, HIPS Rules and found the Custom Ruleset for C:\Windows\System32\Taskmgr.exe. Edited it and changed from Use a Custom Ruleset to Use Ruleset: Allowed Application, OK, OK and Unblocked the Application for HIPS. Started Taskmgr (Cntrl/Shift/Esc), refreshed the Unblock Applications window  and  Taskmgr was back. 

Taskmgr.exe is clean per Virus Total. 

Any suggestions would be appreciated.
