Network Threat Protection: Slow network share

Hi,

I have a Windows 7 computer on the Network running a sage product. 3 other computers (win 7) connect to this computer to run sage (the sage data folder is shared). Over the last few days the 3 users have being complaning about sage being slow. To login in takes 5+ minutes. If I disable network threat protection the problem goes away. I have excluded the data folder but it is still the same. Is there any way to allow unresticted access to the share without uninstalling NTP? I am running SEP ver 12.1.4013.4013

Thanks in Advance
