General Info how to solve conflict between CIS and Avast.

go first to CIS → Defense+ → Defense+ Settings → Execution Control Settings → exclusions → Add → the complete Avast folder.

High cpu usage? this will do the trick but keep in mind CIS is vulnerable to get infected.

1) CIS → Defense+ → Computer Security Policy → Protected Files and Folders → Groups → Add → New Group…(give this group a name, such as Avast). Now click once on “add files here” and Add then Add → Select Fromand → Browse… and add find the wanted folder

2) CIS → Defense+ → Computer Security Policy → select Comodo Internet Securiy and press edit → Customize → Interprocess Memory Accesses → Modify → Add → File Groups → select the wanted group.

Webshield won’t work? This will do the trick

This is one way and the first to try to see if it solves the problem.

CIS → firewall → Network Security Policy → Application rules → Add → browse… → the Avast exe file and as trusted program.

An other solution is to add the group file in application rule by Add → Group files.
