I have recently purchased a QNAP NAS drive, model No. TS653B, which can be used as a standalone unit. It resides on the network/internet. I believe that it has a linux based OS. There is a another vendor's antivirus advertised but I wondered if it can be protected by Trend Micro. I have tried the option to add another device but cannot see this item or sure how to find it. Can you please assist?
