comodo Firewall hips and avast free hips ! Any conflict ?

hi . avast antivirus free 2016 work with comodo firewall ? any conflict ?
and other question . avast hips work with comodo hips ? any conflict ?
answer this two question plz . thanks !

As a rule of thumb we advice not to use two security programs of the same kind together; there is a noticeable chance they will conflict. Do not run two HIPS’s, two network firewalls, two sandboxes, etc…

Comodo Firewall without the HIPS should likely work with Avast HIPS but I have never tried that combination. May be somebody else did.

Edit: I added not to the first sentence. Eric
