Please let us know which of the AV services you turned off and what notifications you are seeing.  Its possible that its either traffic that appears to be comprimised or the device is comprimised and its being quarantined.  Also it could just need a database update.  To do this power cycle your Decos and it should trigger an update.

So that message is related to the intrusion prevention system.  What is happening is there is traffic orginating from those devices that TrendMicro has detected as potential security threats.  There are many reasons why this can occur, for instance we recently had a cusotmer who was using a raspberryPI to do port sniffing on his own network,  the Intrusion prevention system detected this as a threat and blocked the device.  So something as innocent as that could be happening or there could be a potential issue on those devices.  Its best to run a Antivirus and or Maleware scan on those devices to ensure they are working properly.  For the Apple TV try using a more reconized app such as Netflix or Hulu, if possible, or if you have any shows or movies on Itunes trying running those and see if the Apple TV works correctly.  If the devices area ll clean of virus or maleware we may need to collect a bit more information and send it to our software engineers.

The other gentleman in this thread has those features on so it would make sense that it is blocking devices that TrendMirco has flagged as comprimised.  We are working with our software team to see if a override can be included in a future update.  But its not clear if or when that can be done.  

If you have the entire AV suite shut off then all devices should be allowed.  If they are not it would require investigation.
