I try to lunch program from usb device (“keepass.exe” actually). it starts cvc.exe which lunch cvtres.exe and stucks with 99%
cvtres.exe: The resource-to-object converter. This tool is often used to convert a binary resource file to an object file. Native resources usually start life as an .rc file, get compiled to a .res file using rc.exe, get converted to a .obj file using cvtres.exe, and finally get linked into your native application like every other .obj file
Description:
Loaded guard32.dll causes some .NET Framework components to not operate properly.
Steps to Reproduce:
install AutoCAD 2008, install CF (Comodo Firewall), set D+ to training mode;
launch AutoCAD, when all CF components (drivers, service, guard32.dll, gui) are up and running;
Actual Results:
Cvtres.exe hits 100% CPU usage and stays there forever (see screenshot), until terminated.
Build & Platform & Other security apps:
XP Home SP3 x32 (all latest updates), CF 3.0.24.368 (fresh install without toolbar), CMF 2.0.4.20.
.NET Framework 2.0 SP1 + RUS language pack.
Additional Information:
Preventing guard32.dll from loading in memory at system startup (renaming, deleting) completely solves problem for me. Note that other system and CF settings are unchanged, what make me think it is definitely related to guard32 library.
Most likely, CF 3.0.21 didn’t have such problem.
Install Visual Studio 2008, New | Project | Visual C# | Windows | Windows Forms Application, and Build,
then Cvtres.exe hits 99% CPU usage and stays there forever, until terminated.
Same problem here with this exe; yesterday I updated the firewall to the last version and soon realized that two different processes were loading ramdomly on memory moments after the start up. One of them was the cvtres.exe, with a 25% of CPU usage; the problem was that after this first one, two and finally three more instances were loaded -25% each- so the CPU usage soon reached 100%.
Today I decided to go back to the old 3.0.21.329 version and so far -3 hours later-, everything is working fine.
Even the port 135 seems to be closed now (at least it´s not listed in the “Active conecctions” window: it was “listening” with the new version). Read this report to see what I mean. https://forums.comodo.com/
BTW, I don´t have installed the Safesurf, and the firewall is running with the default config.

Uninstall CFP_Setup_3.0.24.368_XP_Vista_x32.exe, and Reinstall CFP_Setup_3.0.22.349_XP_Vista_x32.exe, everything is OK.
MY OS: XP Home SP3 x32 (all latest updates).
Reproduction :
After install CFP_Setup_3.0.24.368_XP_Vista_x32.exe, Defense+ Security Level set to “Disabled”, “Monitor Settings” uncheck all, click Apply button.
Run cmd.exe open a command line window, then save attachment cvtres.txt to anywhere and goto there rename it to cvtres.exe and run it, it will hang.
Uninstall CFP_Setup_3.0.24.368_XP_Vista_x32.exe, and Reinstall CFP_Setup_3.0.22.349_XP_Vista_x32.exe, everything is OK.
Attachment cvtres.txt MD5 hash value:
e0d21bee6dae44a7c6e1896d7a8c7463
It’s a C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\cvtres.exe.
No SafeSurf here installed. Didn’t try to disable CMF and it’s driver though, but don’t see any reason, because in my case it is definitely connected to guard32.dll.
Edit: thanks for the tip, maybe one more CF-CMF confict will be revealed (one already reported).
Will try to play with CMF when reach machine with AutoCAD installed.
with CFP_Setup_3.0.24.368_XP_Vista_x32.exe or CFP_Setup_3.0.22.349_XP_Vista_x32.exe installed if I try to build a project in Visual Studio 2008 the build process runs forever (VS gets frozen); the cvtres.exe process (launched by devenv.exe, i.e. by VS) takes 50% CPU time; CF does not show any messages and does not ask any questions; if I kill the cvtres.exe process visual studio becomes responsive (but the build remains incomplete, of course). This happens even if d+ is not installed and both VS and cvtres.exe are specified as trusted applications.
With ComodoFW_3.0.16.295_XP_Vista_x32.exe VS builds run without any problems. I have not tried any other versions of CF.
workedaround for me too (:WIN)
i had to put cmd.exe and mcbuilder.exe in the CMF 2.0.4.20 exclusionlist.
Problem “gone” remove them from the list and the problem is back.
I have no idea what is starting cvtres.exe, it seems to appear on its own. Example: I was browsing the Web (Firefox 3.0RC2), while recording a VHS tape to disk (Honestech VHS to DVD,) with my email program (Thunderbird) and WordPerfect open.
Because I’ve had problems with cvtres.exe for three days or so now, I have the Task Manager open to show the CPU use. Suddenly, the computer cooling fan started running faster, and the CPU use jumped from 40-50% to 100.
I closed TWO instances of cvtres.exe, and CPU use dropped back to 40-50%.
I thought that I had told Comodo to ignore cvtres.exe, but it is quite possible that I did not do so properly, as I’m not at all certain how to do that.
Thus, more detailed instructions on how to fix this problem would be appreciated, along with any hints as to what might be calling cvtres.exe. (As far as I can tell, none of the open applications use the .exe, as turning cvtres.exe off in the Task Manager has no effect on those applications.)
I just had this problem too with mediaportal HTPC software - using CMF, cvtres.exe was reaching 100% cpu and doing nothing - after adding to the exclude list it’s fine
