Might be time to switch to Comodo's free software (I'm just waiting until the Anti-Virus leaves beta to switch from AVG Free). http://www.comodo.com/products/free_products.html
Comodo (free) has an excellent firewall. I believe still only no.2 under Online Armor's (paid) according to in-depth testing by Matousec. Avast (IMHO, and many reviews) is a superior AV program to Comodo's in the free software category. I have used NOD32 (paid) for 5 years and found it to be a superior AV program, and the new 3.0 version has a new and more user friendly UI for newer users.
