Should I still run windows firewall with avast free. I can't work out yet if avast free has it's own firewall.
Sorry for sounding dumb but early day for me.
The Network Shield in avast! free isn't a full firewall it monitors common worm/exploit ports. So as craigb said you need to leave it enabled.
A further point is what is your OS ?
The various OSes have slightly different levels of protection; XP firewall has zero outbound protection; Vista/Win7 firewalls have outbound protection, but it is disabled by default. Even when the Vista/Win7 firewall does have outbound protection, it is rules based (you have to create the rules) and not very user friendly.
