X64 system freeze (crash) with app in full screen (v3.13......)

Hello guys !

I read several post about crashes, freezes, black screens with games in full screen… All relate to 64-bits (graphic card ATI or NVidia). I have tried some games with CIS in vista x64, server 2008 x64 and win7 x64 this problem is common for all x64 systems.

Answers to resolve blocking does not satisfy me.

A note to gamers (https://forums.comodo.com/empty-t20008.0.html) is the worst of all and contrary to common sense.
Activate the Training Mode pretty much renders the whole CIS useless… and even less if you forget to return it !! I read this solution several times, IT’S DANGEROUS, VERY DANGEROUS… Unfortunately this solution is proposed and the topic is closed.

I would prefer that the problem is completely solved by Comodo programmers.

I have installed a clean x64 french Windows 7 in virtual machine with CIS without modifiy options (defense + and firewall in safe mode).
When a game is launched:

  • the screen is freezed (black or not)
  • the keyboard does not respond (ctrl-alt-del, ctrl-shift-esc, windows key… caps lock & num lock do not change the LED of keyboard)
  • the machine respond to PING
  • the CPU usage does not seem important
  • if music is played by Win media player it does not stop, but, strange, it stop with XMplay player

I think there is one (or more) warning in the background but why the system seems freezed ?
For test I lowered the time “Keep an alert on screen for maximum” (defense+ > advanced > defense+ settings > general settings) to 10 seconds. Wonder ! There the system is freezed only for 84 seconds (and the game works). Then I change this time, the freeze is proportional (time=100 sec ; freeze=804 sec…)

I have also installed a clean x32 french Windows 7 in virtual machine and strangely with the sames games I have no warning from CIS.

First: until resolution of the problem, I suggest to the gamers to lower the time of alerts (defense+ & firewall) to try their games but not the trainer mode !!

Second: CALL > someone uses a 64 bits system without problem with full screen games ?

third: Send your testimonies here so that the problem is solved (indicate processor & graphic card…)

Thank you

A Game mode has been requested several times in the past in the Wish boards:
Gamemode
When will COMODO Internet Security have GAME MODE FEATURE?

I assume the devs are very much aware of this problem.

As a workaround you can add all the .exe and .bat files of the installation folders of a game to My Own Trusted Files. CIS will then automatically make rules for just the game its self.

Hello Eric,

It’s only a solution for a well known program. If I used only applications well know, I do not need CIS.
It’s a DANGEROUS security hole for COMODO !!

...but it's a old problem ?!?! We want only see the warning and decide by ourselves. Whether the program is reduced to display the alert or the keyboard responds to the common keys (who reduce game). I think this problem (crash) is sufficiently important that it be solved otherwise than by little do it yourself driving to security holes (the last post on this problem has been viewed 13,400 times since march 2009).
