I need a free firewall, which one is the best. In the past zone alarm blocked all internet connection and I had to remove it. I had the same problem with nortons and the ntl helpline were familiar with this and advised me to remove it.
I also had ZoneAlarm and it started playing up, so I uninstalled it. I went for Sygate as posted by stalion but after a while I started getting problems again. I then tried Outpost as recommended by the FE but that also started giving problems. I have now gone back to the latest version of Zonealarm and so far it has been very good. I am on NTL Broadband.
