This is a concern because the rate is quite noticeable although comodo firewall feels extremely light
I used process explorer, process hacker to monitor the i/o rate and they both have the same values

I use CS's configuration with some personal tweaks

Screenshot in idle, no program running ~250KB/s

i think all scanners ( av, antimalware, firewall etc) had the same system they reading system constatly svhost also wich is running always
true but the problem is CF is writing a lot of data with significant rate at 250KB/s regardless of what we are doing
even when I closed CF via the tray icon, the CF's process was still running and writing at the exact same rate

as you can see in the screenshots, avast and svchosts's values were 1KB/s in idle

he hE-HE it is this the price in exchange on get high security. dont forget. I come back and I repeat, the security software can have the malware behavior instead of having a satisfactory experience stressing the components of the PC. You should talk to the technical Comodo support to obtain the light in your mind.

On my system CF is quiet...

thank you for this confirmation
maybe because I used CF to block connections of too many processes including svchosts which led to this high disk consumption
I will try to use the default proactive configuration with minimal tweaks

What have you got to lose?
I have a long list of blocked processes similarly to syshardener's list
+ chrome: allow only port 53, 80, 443, 8080, block everything else
+ svchosts: allow only port 53, 67, 80, 443, block the rest
+ ... many more

perhaps blocking svchosts causes this constant disk consumption because svchosts is always trying to send something to microsoft and some other domains

I will try to revert to the default settings and start investigating which change I made was the culprit

Evjl- Keep it simple- Trust Me.
Reset it back to default, does it still do that?
unfortunately, after re-installing CF and changed it back to Proactive profile, performed CS's config., a scan for unrecognized files -> rebooted -> nothing has changed. CF is still constantly writing ~200-250KB/s

not sure if there is any conflict with avast or just because I'm using HDD, not SSD

Probably the HDD is the problem.I had the same problem with all COMODO products. I did not find a solution. And with COMODO cloud the same problem. Ido not use anymore COMODO products

Windows Firewall for the win; no high writes

Quite True- something that provides no meaningful protection tends to be the quietest.

Evjl- Please understand that any Windows build, even at idle (without any User Input or any Apps being open) will be doing stuff in the background. CF MUST monitor this stuff. If it did not, the pathway to breach would be obvious (for example, a pre-existing malware file with a prolonged sleep function). The activity of CF will also be increased if a browser, on a page with active content, would be open; also if one uses a secondary AV scanner that is active.

In short, if CF was always idle I would never use it, and it would make Ophelia just Drool (I'm sure she would submit a paper to Blackhat USA, but they don't accept papers from Cats- prejudicial Bastards).

Did you try disabling system protection and delete all restore points to see if its reducing the constant disk usage? It might be calling Create restore point process to make periodic snapshots just in case.

It's really quiet for me but regardless 350KB/s is nothing even for an hdd. You are not going to notice any slowdown from that and i am surprised that you use avast and notice CF. Last time i checked avast, few years ago, it had the worse dirk write in the history and it was in the MB range and not KB.
