PC crashed WhoCrashed shows cmdguard.sys as issue

This laptop had an issue a few days ago where it couldn’t boot into Win7 anymore kept saying device inaccessible and then when that was fixed Missing or Corrupt application and pointed to Windows\System32\Winload.exe. So I just reformatted it about a day ago and installed all the updates and downloaded copy of CIS from site and installed.

Today I was listening to live stream from a radio station via FF14 and then the sound cut out and I figured it was maybe the sound driver and then FF14 closes, shows desktop for a few, and then BSOD. When I log back on looked at what crashed via WhoCrashed and this was what it says:

On Thu 7/26/2012 your computer crashed
crash dump file: C:\Windows\Minidump\072612-25562-01.dmp
This was probably caused by the following module: cmdguard.sys (cmdguard+0xD278)
Bugcheck code: 0xF4 (0x3, 0xFFFFFFFF85884558, 0xFFFFFFFF858846C4, 0xFFFFFFFF82C24DF0)
file path: C:\Windows\system32\drivers\cmdguard.sys
product: COMODO Internet Security Sandbox Driver
company: COMODO
description: COMODO Internet Security Sandbox Driver
Bug check description: This indicates that a process or thread crucial to system operation has unexpectedly exited or been terminated.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: cmdguard.sys (COMODO Internet Security Sandbox Driver, COMODO).

I did a ran chkdsk and it fixed MFT space and nothing else was found. Ran MemTest just to make sure wasn’t the ram and came clean. Just did a Computer scan with CIS and nothing detected, there is also no available updates via MS Update.

I’m just wondering if this is a bug? I disabled Sandbox after that crash to see if it happens anymore and will keep forums updated if it does happen again.

So far so good. Tho this stupid Flash Player plugin 11.3.300.257-11.3.300.265 is ■■■■■■ crashes often in FF14, while watching some videos or streaming music. Especially when making it full screen, sometimes it works sometimes it crashes. Doesn’t happen with, Cant win em all.

Does this bring a solution?

It seems that it stopped the BSODs and sandbox is enabled again. Been alright since updating but the flash still crashes in FF when trying to open full screen but that’s a flash bug I believe.

There has been a lot of Flash trouble in Firefox lately:




Strange, I haven’t had one crash with Firefox and Flash.

Same here. I’ve had no problems either, but numerous others have. Go figure! :-\

With hardware acceleration being used by FF and Flash these days the graphics drivers become an important player in the stability of browsers and Flash plugin. This could be an explanation why instability hits one group of users and not others.

My video card is an older nVidia card which has no hardware acceleration. I’m so happy that it doesn’t! Many Firefox users have hardware acceleration problems within Firefox and now it seems to be causing trouble with Flash. It’s so nice to have an older machine without all of these “high tech” problems!

You are not alone.
During a certain era, systems were built nearly bullet proof. :-TU

I’ve had this machine running, pretty much trouble free, since 2003! I’ve never had to reformat, my WinXP installation has been running since 2003 as well! The only problems I’ve had were a bad power supply and one bad memory DIMM. The memory was a Kingston strip, which they gladly replaced for free (lifetime warranty)! Nice company to deal with if you need memory.
