How to exclude files from being scanned

 Currently, we are working on a project that we need to avoid significant slowness to the project by having Symmantec Anti-Virus not scan items going to the following server, 3 paths, and its subfolders:

server: DHITSEECAPPIP32

paths (please include subfolders):   D:\IAS

C:\Program Files (x86)\InputAccel\Client C:\Program Files (x86)\InputAccel\Server\Server\binnt

How do i exclude certain folders from the scan?
