You should be able to keep Norton 360 from scanning the WD folders (including those within the main wd folder) by starting norton 360, then clicking on "settings", then "antivirus protection". Then, on the "scans and risks" tab under "exclusion/low risks", click on configure next to scan exclusions. Then under scan exclusions click "add". Next browse to the folder that WD is installed in, and with it highlighted check "include subfolders", then click OK. Then under auto protect exclusions click "add", again browse and select the wd folder, and be sure to check "include subfolders". Click OK, then under Apply click OK and again under apply click on close. Those are the instructions found on Norton's web site. Personally, I agree with Niko. Dump Norton. I did several years ago and haven't looked back. There are other better, cheaper choices out there.
