I have avast internet security suite and it works well.
Before, i had comodo and my wifi printer did not work with my computer with windows 7.
I chose the average level with the avast firewall and everything work.
The only one problem was with my computer with vista 32 bits, i had to reinstall the printer driver and it was ok.
I think that the free firewalls aren’t very easy to use and does’nt work well.
