I have problem when applying hotfixes for my accounting software (Maestro). The hotfix is not a Windows Installer package but a autoextractible package .mhf format.
With Comodo 8.0 temporary disabled, the problem is still there. Same thing with disabled HIPS and disabled Sandbox. With 7.0 version, I didn’t have this problem. For the moment, to apply hotfix for Maestro successfully, I close Comodo Antivirus from the taskbar and I kill in Windows task manager cavwp.exe and cmdagent.exe.
Problem when applying Maestro hotfix since Comodo 8.0 installation:
Did you get get a popup asking if you wanted to trust the installer? Are popups enabled? What are the settings of your configuration? (Internet/Proactive/Firewall/HIPS/Sandbox/Viruscope/etc)
The hotfix rollbacks only on executable and DLL files extracted from the .mhf file. Is Comodo changing the date/time of the extracted files? Also, extracted files from the MHF files are uncompressed in temp folder, not directly in Maestro installation folder.
Hotfix is applying correctly when cmdagent.exe is killed.
