Windows crashes with error code 0x000007E

Hi, I was hoping someone could help, my pc starting randomly rebooting on Saturday morning, at irregular intervals. The error code reported on the BSOD was 0x0000007E (0xc0000005, 0x804EF2F4, 0xF7A5FA60, 0xF7A5F75c).

The event viewer shows:

Can anyone shed any light on the likely cause of this?

Comodo firewall is the problem. It's very new, when did you install it?

BugCheck 1000007E, {c0000005, 804ef2f4, f7a73a60, f7a7375c}
Probably caused by : cmdguard.sys ( cmdguard+e0c7 )
Image name: cmdguard.sys Timestamp: Thu Oct 23 05:33:24 2008 (48FF8E14)

Been using it for a while, but recently updated it.

Same 0x7E BSOD on my WinXP SP3 box in cmdguard.sys after updating Comodo Firewall to version 3.5.....

Started to get BSODs with the error code 1000007e, parameter1 c0000005 since Nov. 3, 2008. After running windows debugging tool, I was able to analyze the minidumps and found out that the cmdguard.sys was causing the BSODs.

I uninstalled the 3.5 version and went back to 3.0.25.278 and no more BSODs out of cmdguard.sys.

I also uninstalled Comodo Firewall, version 3.5.55810.432 and re-installed 3.0.25.378. No more BSODs sofar. Usually when I plugged in a USB after start-up of Windows, I got a BSOD right away. Tested this scenario this morning and didn't get a BSOD. Certainly a good sign. However, I will wait a few days to see whether I will get any BSODs again. Will report again early next week on any continued success.
By the way, this TechSpot community is fabulous. Really helped me getting to the bottom of my issue and probably saved me money by not having to take my computer into a shop. Thank you all for participating. Is really encouraging!
