How do I create an exception for a .dll file?

Hello - Symantec Endpoint Protection  is flagging Cal-LIMS 10 DLLs as Malware. See attached files.  Cal-LIM signon page works only after disabling SEP service or excluding .DLL from SEP on each desktop. How do I create an excpetion to allow the .dll file so users can sign on to the Cal-LIM sign in page?

thanks
