about Comodo Firewall Nov 2015

Comodo try to install a Browser replacement(Chromodo) It try also to replace your DNS with it own DNS. Just after installation, you will get anoying advice pop up. And a secure pop up is alway present on my desktop after install. He install GeekBuddy a messenger which will pop up you when you have an app crash... (wow in a firewall, is this serious or what ?). Sound not very serious...

The best free firewall for windows, period!


Comodo, fairly-good reputation over the years.

about Comodo Firewall Jun 2011

I used this for quite a while on my older Win2000 and WinXP systems, and it was quite effective at keeping my clients out of the dark recessing of the internet. On the newer systems, running Vista/Win7 or a popular Linux distro, I tend to opt for the integrated firewall for convenience sake. However, as needed, I wouldn't hesitate to trust Comodo, given their fairly-good reputation over the years.
