Endpoint Protection

Hello, 

We’re facing some issues regarding the Symantec EndPoint Protection – it causes crashes in ANY Winforms application quite randomly.

This happens when DEP is enabled, because the sysfer.dll is injected to those processes.

We found out that if we add exceptions for those processes in SEP it does not crash, 

but we would like to know what is the propriate way to handle this issue and avoid crashes in WinForm applications.

(The issue happens when the processes are compiled in VS2010 or VS2013).

Thanks,

Keren

As you already did, excluding the processes from "Application Control" is the best way to avoid this issue. But make sure that the exclusion is added only for "Application Control" and not for the normal virus scans.

Submitting the file to Symantec as false positive will only help in cases where the Virus san or the SONAR is causing the crash. So I believe that won't help resolve the issue in your case.

Please read thru this:

Creating Application Control Exclusions in Symantec Endpoint Protection 12.1

Hi Seyad,

Isn't that a bit weird that the Symantec Endpoint Protection causes crashes on WinForms applications?

We've been facing the same issue as well. 

It's quite absurd that the only solution is to exclude these processes from Application Control.
