SEP causes WinForm processes to crash

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
