i had a problem where the comodo agent couldn’t run , i ran the diagnostic couldn’t fix the problem , tried the comodo uninstaller tool couldn’t run due to revoked cert ,
i have a report created by the diagnostic tool i can send it if it help
fixed the issue by reinstalling windows
There was a certificate issue with the previous version. You need to download the latest version from this topic: New Version 12.3.4.8162 Available
You need to use the old Unistaller Tool to remove remnants of CIS: http://download.comodo.com/cis/download/installs/ciscleanuptool/CisCleanupTool_x64_3.1.0.45.exe

the problem happend with the lattest comodo build
could it be malware ?
Unlikely. Did you uncheck Trust Applications by trusted vendors in the file rating settings?

There’s a recently discovered bug with this and recent versions and causes CIS/CF to not trust it’s own files and you end up having to remove it in safe mode. There isn’t an issue with the old .8012 version which is just as secure as the latest version even though it’s 4 years old. https://forums.comodo.com/t/comodo-internet-security-2020-v12-2-2-8012-released/320209 just make sure you when installing that version, you uncheck the other software in the installer options with that version. Comodo Dragon is good but behind current chromium build, secure shopping is no longer being developed and Internet Security Essentials only worked with internet explorer and early Firefox versions.
