Yes, I have some clients using it. Seems to be fine on the workstations, however on one customer we had to remove it from the server. They are Sage 100 Advanced 2014 running Application Server mode, Microsoft Server 2003. It was slowing everything down to a halt. As soon as we removed it everything went back to normal. The workstations are still on it. Love the AV product, catches a lot of things Trend Micro and Symantec never even saw.
