Avast 8 free av and comodo firewall 5.12.Assistance please.?

Hello.
I currently run avast 8 and comodo firewall 5.12.

Could anybody be so kind as to suggest what exclusions i need to put into place please.
I have excluded some parts of each product,but is there any particularly important exclusions i need to put in place.

I have turned off the comodo sandbox and use the avast one instead.
Execution control in comodo is turned on and set to untrusted.

Thank You.
