Option to scan only harmful file extensions in real-time with CAV

1. What actually happened or you saw:
In Comodo Cloud Antivirus there used to be a option at Antivirus Settings for “check only executables, libraries and scripts”.

2. What you wanted to happen or see:
I would like to see this option being added to CIS Antivirus Settings for Real-Time Protection, not only manual scans.

3. Why you think it is desirable:
Would reduce a lot of Disk Usage from cavwp.exe which keeps grinding the disk at random times, scanning files with harmless extensions.

4. Any other information:
Since it appears Comodo will not reduce this huge AV database size of >400MB anytime soon, this option is highly desirable for reducing the performance cost associated with the AV module.

add an option in antivirus to use only cloud scanning instead of installing the database like in CCAV?
theoretically already exists, but unable to disable database update. Disable database update, I think it would be enough to program it in the update options: Comodo Internet Security Software Updates, Download Software Updates | COMODO :-\
