I've got an 895 too, and I run Norton Antivirus as well. I've had no problems setting up my remote and do not need to disable Norton, both co-exist and simply work as they should. Cannot comment on the other Norton products except to say that I had to ask a customer of mine to change to another system as Norton Firewall would not allow her to connect to a web server within her home network regardless of what was done with Norton. I would suspect the problem lies with Norton, not the remote.
