Hi nic,
 
Is it also popssible to prepare the setting that mounted drives are excluded from scanning?
 
Background: On our customers tenant I've created three different policies
1. For Users
2. For development servers
3. For production servers
 
Now, I would like to exclude mounted drives from beeing scannend by every user because of the giant volume of network-traffic. Can I genereally exclude them for all clients in the first policy?
 
Kind regards,
 
Sven

You should able to do that as long as they have mapped drive letters. Let me know if you run into any issues. It's not like Webroot scans every file on the drive anyway. It'll only care if you're running executables from those drives.
