Comodo Free FW with Avast/BD AV

I’m using Comodo free FW with BD AV plus, with HIPS, heuristics command-line and Shell Code injection Off in Comodo. I get alerts from the cloud AV though in Comodo. Should I do anything else to prevent problems/conflicts? i exluded Comodo folder in BD scan settings both on-access and on-demand.
Any tips to use Comodo free FW with other AV like Avast AV Free? Please let me know asap.
