I uninstalled my Norton and installed Avast! but now do not have a firewall to my knowledge besides the default one that windows had. One of my friends recommended comodo firewall to use. I have a couple of questions with this program though. Is comodo the best free firewall out there or anyone else have a different recommendation. Also, I have a wireless network. Is it difficult to set it up to allow the other computer w/o allowing all computers access?
