I have a mapped drive on my system that has 2.5 TB of files, mostly my photos (www.stevenvona.com). Everytime it scans it scans this whole drive and I want to stop it from doing so. When I go into security center and select custom scan and only select the folders I want to scan it then click apply. When I go back in it is reverted back to checking everything. How do I stop virus scan from scanning my network drive?
