You can exclude scanning of all the mapped network drives and attached removable drives. You can also exclude individual files, file types, and folders from security scans to improve scan performance and prevent false positive detections. Scan exclusions apply to all devices in the group(s) that the security policy is applied to.
This setting applies only to Windows, OS X devices, and Windows servers.
Although scan exclusions can reduce the time and resources that are required to complete security scans, excluded items are no longer protected from viruses and other security threats. Consider the trade-offs before you exclude files or drives. If necessary, you can remove them from an exclusion list to make sure that they are protected.
Excludes all the network drives that are mapped on desktops or laptops.
When you disable this setting, networked drives are scanned through every device that maps to them. Consider the performance issues on the devices and your network before you include mapped drives in scans.
Exclude Removable Drives (Windows Only)

When you enable this setting, removable drives are no longer scanned for viruses and other malware. Consider the trade-offs before you exclude removable drives from scans.
