SEMP 12 - Exceptions not working

Hi,

I'm trying to exclude some .DLL files from being scanned.

I created an exception item indicating "NONE" as prefix variable and checked all the types of scans.

Unfortunately, I can still see in the risk log of the clients that the files are being detected as a risk and getting quarantined.

Does this has something to do with the prefix variable ? How can I exclude a file wherever he could be located ?

Thanks !

Regards,

Eric
