I find that version of the Uninstaller doesn’t work that well. You can download the previous version as linked in this post: https://forums.comodo.com/t/official-comodo-uninstaller-v3-2-0-82-released/314767/83
Beyond this, Comodo does leave some remnants behind. Both 8012 and Beta Leave Startup and Event Viewer entries which can be removed via registry:
Startup and EventViewer entries can be deleted from registry:Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
The current CIS Beta leaves behind drivers:
Removing cmdguard.sys and cmdhlp.sys drivers is done by running CMD as Administrator. Entering the below to get the driver list:Dism /online /Get-Drivers /Format:
Table
Make a note of the Comodo Entries oemXX.inf number and then enter the below for each entry to delete them, replacing the XX with the corresponding oem number.
pnputil /delete-driver oemXX.inf /uninstall /force
and then reboot.
