Are you sure you installed the AV portion? Because CIS will still do its initial malware scan even if you don't install the AV.
From the CIS folder in your program files, run the shortcut called Uninstall or Upgrade. You can reinstall the AV module from there.
Tried to find either shortcut, but could not find one named either.
Went into the file system and ran C:\Program Files\COMODO\COMODO Internet Security\repair\cfpupdat.exe which did an update to no avail as the AntiVirus module did not activate. I still only see Summary, Firewall, Defense+ and Miscellaneous as the icons at the top.
Suggestions?
Thanks.
