first thing to say i already searched the forum and the old theads related to my problem do not have any working solution.
My problem is that somehow (since the last comodo update to v5.4) there is a guard32.dll attached to my applikation that blocks debugging (just tried gdb) with a SIGSEGV segmentation fault.
The runntimestack at this point looks like this:
0 ?? C:\Windows\SysWOW64\guard32.dll 0 0x100127c3

My system is running windows 7 x64 (Build: 7601 sp1) all updates installed. Using CIS (5.4.189822.1355) (no other av programm or something like)
What i already tried.
Uninstalling comodo: debugging works.
Reinstalling comodo: debugging blocked
added all debugger files to my save files and also added them to defense+ memory interception(dunno how its called in the english version).: debugging blocked.
Disabled sandbox and permanently disable D+: debugging blocked (this worked for me pre 5.4 CIS)
Disabling windows DEP: debugging blocked
I've read something about unloading guard32.dll but all those posts were related to windows xp and as windows 7 uses a new way to handle memory i couldnt find some way to unload it.
Thanks all in advance.
