No other freeware product causes as much angst to users, whether in installation or day-to-day use, as a firewall.

This article gives you a selection of the best free software firewalls available.

If you don’t decide to use one of the firewall products in the article, at least remember to turn on the Windows firewall. Be sure to use only one software firewall at a time.

Additionally, most products highly recommend uninstalling other third-party software firewalls before installation (and disabling the Windows firewall if they don’t).
