Sometimes a strange( STOP sign) Icon appears over Comodo Icon in tray. i am uploading the screen shot, as it appears to be mysterious.( No explanations is found in HELP manual).
this icon disappears when you logoff( not restart ) and do logon again.
-Earlier i thought this icon is coming from remains of Avast home, but it is not the case, as Inactive icon for Avast( in tray) is left handed.( I also used their uninstaller to remove it)
I also noticed that while installing CIS it didn’t asked me to scan the system, just before rebooting. To be doubly sure I reinstalled it . On second time installation it also didn’t asked to scan the system.
Make sure cmdagent runs as admin and see if that helps.
Try updating the Comodo Internet Security Helper Service (control panel, admin tools, services, right click on “Comodo Internet Security Helper Service”, properties). The logon Tab for the Service should currently show Local System Account and Allow service to interact with Desktop. Set This Account with your Logon ID and Password (+Confirm) and then reboot.
