COMODO, today, only worth it for the sandbox and firewall, with changed settings is very difficult to contaminate the PC. Web defense is very weak (maybe more than antivirus). It gives the need to use extensions in the browser (I chose Avira Browser Safety).
I have used Comodo in the past.
I was satisfied with it's performance, light on system resources.
Sandbox is great and it helped me even with ransomware.
But i really enjoyed HIPS when i begun to understand how it works.
For me HIPS is great tool to train your self to learn more about security.
I use CF + Sandboxie (non system disk) + Shadow Defender on boot (system disk) on my old Windows XP laptop. This is rather locked configuration, but I can install and update programs in separate sandboxes with active Shadow Defender.
CF is configured with @cruelsister settings (but Comodo Sandbox is set to block untrusted).
I like very much the simplicity and effectiveness of Comodo Firewall. I do not bother about Comodo antivirus, HIPS and other stuff.
I do not use CF on computers with Windows 10, because of the possible problems with sandboxed system files after Windows updates.
Currently using comodo internet security 10 tweaked to my likings , also using dragon and ice dragon no problems at all , Well adguard is making browsing a bit slow. I am happy with my current setup. So I Will not change untill it is becomming boring
I used CFW for several years. Good protection and fairly straightforward to use. Unfortunately each clean install of a new version caused more and more problems until, despite following Chiron's clean install guide (link below) to the letter, it would not install and caused multiple BSODs and a lot of time and effort to get things up and running again. So I was forced to go to another product.
Even if things go as planned, it is still a ridiculously complex and time consuming procedure, and if it goes wrong, as I found, it can cause a lot of grief.
If you are already using Comodo and are happy with it, fine. If you have never used Comodo and are thinking of using it, my advice would be don't. Quite simply, it is far more trouble than it is worth, especially when you try to install a new version.
