i have installed avast 4.7,and i runs quite well.
but i have some questions .
if i should install a firewall else to protect my computer???
thank you ! :

I prefer Comodo Firewall Pro:

It works just fine with avast!, the firewall is free, but the firewall doesn’t work on Win95, Win98, WinME. Currently it doesn’t work on Vista, but the new upcomming version (v3) will work on Vista.
