Hi there, I am really happy with Comodo firewall and think it is THE best one to use!
I play an online game called World of Warcraft and I had my account keylogged before, lost so much stuff
back then I didn't have a clue about security and only had a Windows Firewall in place. I did A LOT of research and every review and PC mag seemed to recomend Comodo as the best free firewall. I got it and (2 years later) haven't had any problems since!
I will write a recomendation on the WoW forums about Comodo too. In the securtiy articles on their forums players seem to recomend Zone Alarm a lot and I think Comodo is better than Zone Alarm as it does a more complete job and by the reviews I read passed many more hacking tests.
This is what I recomend for best protection:- COMODO Firewall!!! - Firefox web browser with no script addon - Malware Bites scanner - Avast scanner - COMODO Virus Scanner (free with firewall) All = VERY safe Computer!
Hope this will help and thanks for providing a great service.
