Blue screen(0x1000007e)

OS:WindowsXP SP3 32bit (Japanese)

=Since the following texts are translating with translation service, there may be a portion with an amusing meaning.=

After installing the firewall of CIS, while operating under starting and PC, a blue screen came to come out.
Otherwise, the blue screen was generated when having started iTunes.

When it continued carrying out the tab of iTunes which started iTunes to the trial and came out in the taskbar at it continuously, it turned out that a blue screen is generated.

This problem was not generated when CIS (Firewall) was uninstalled. Possibly, CIS also regarded the error in starting and PC operation as whether it is the cause, and wrote it in the forum.
Incidentally, the problem was not generated when it was COMODO (3.0) before CIS. The contents of the detailed blue screen are written below.

0x1000007e (0xc0000005, 0x804f24fe, 0xbacffa68, 0xbacff764)

Thank You For Giving Out Info :slight_smile:
Can you attach your Dump File?


Thank you for the reply.

Also after updating CFP (, it turned out that the same error comes out. A version is the 3.5.55810.432 [ same ] as the version to which the error took place by Firewall of CIS.

Although a dumping file is attached, it is a thing of the error which occurred when it rebooted after updating CFP.

Thank you,


Thank you very much here.
Solution of this problem will be desired early also for one day.

I have the same issue - iTunes causing a BSOD connected with cmdguard.sys

I have posted crash dumps here;msg238741#msg238741

Confirmed - after uninstall of Comodo, no more BSODs.

I have had BSOD’s with this number. Unfortunately it doesn’t state an error name nor a file that may be causing the problem. Always assumed it would be CIS. It happens both on XP and Vista for me.
