By the way, Egemen, what about existing installations of Comodo Memory Firewall? Any risk of conflict if updating CIS whilst CMF is already present separately?


Just awesome. :ilovecomodo:


Now I can sing:

Well, I’m a lucky man
With fire in my hands

both Defense+ and the Network firewall report not working at all here after a fresh install. I was using beta before, which worked fine on win7b7000… D+ now reports it is disabled, suggests I start the diagnostics tool, which reports there is a problem it can try to fix, but which then fails to do so, generating the attached report.

Summary/Rephrase for dramatic effect: Both the Firewall and Defense+ are not working here (in win7 x64)

(Uninstall/reinstalling a 2nd time did nothing, nor did rebooting)

They wont conflict. But you do not need both of them for Buffer overflow protection. So if you have this CIS, you dont need CMF.

PLease keep this thread
updated (if necessary).
Is it still valid? :comodo110:

I have the same problems with current CIS, I get an error message and my whole windows profile is messed up bad… defense + is the cause, let’s see if this new release has solved some bug issues…

oh great, just as my windows crashed >:(


Great, thanks. :-TU

EDIT 1: I’ll make an FAQ out of that, it’ll be useful the upcoming days/weeks.

EDIT 2: Here it is. :slight_smile:

Oh Dear
Same problems as in Beta.
CPU runs at 28%
Some programs will not open.
Have tried rebooting,makes no difference.
I have gone back to v.439
Maybe i will try again at a later date

Great News, Internet and Downloads dead slow ! Very sad. CIS not optimized, I would rather wait to next released

Well, so far so good on my computer. Haven’t gotten the false positives I got with the beta yet, either.

great job!!! (V)

only one question: I’ve uninstalled safesurf because of the integration of the memory firewall, but during the installation, it asked me to install it again. I’ve said no. right choice?

again, great job! thx!

Congrats Comodo, :BNC :BNC :BNC :Beer :Beer :Beer

2 day delay. Not bad! I expected between 1-2 weeks personally. Installed it and every thing is running great so far. (:KWL)
