guard32.dll cause application crash with ProxifierPE

I’m using COMODO CIS for a long time with no problem at all.
But from few months ago I’m performing big problem with usage of comodo and ProxifierPE (

If i run proxifier, every application I start after that crash after few second (firefox, thunderbierd and so on…).
After a lot of invertigation with the support team of proxifier, the problem was isolatet and is related to “guard32.dll”.

In fact if I manually remove the registry entry: “AppInit_DLLs”=" C:\Windows\system32\guard32.dll"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows

After that, All application works fine even with proxifier.

Can someone tell me what’s is this dll and if is really needed by CIS.
After I delete the entry from registry… the CIS seems still working fine. Is it possible ??
Can I permanently remove this entry ??

Or in alternative how can i solve this problem ??
thx in advance

This sounds like a bug to me. I will move your topic to the bug boards so the devs can pick up on it.

In the meanwhile read IMPORTANT: HOW TO SUBMIT BUGREPORTS (READ THIS IF YOU WANT THEM FIXED) and add the requested information to your topic for as far as it wasn’t already provided.

The problem exist even with Windows vista 32 bit than windows 7 32 bit (both up to date).

The release of COMODO is: 3.13.126709.581

Virus definition: 3711

Could you please provide us with the required information as requested? That will help to devs to reproduce your problem so they can start fixing it.

I attach the report made on my Windows 7 notebook.

On this PC, after I have disable the guard32.dll the ProxifierPE works with no problem.

Tomorrow I try to attach the report made with the Vista Notebook. Here, even with guard32 disabled the ProxifierPE, do not crash, but do not workat all (do not proxify ).
