I posted the following question on their forum. I want to put it out here too. "I've been using the A-V for three years now and just today noticed "Idle Time Optimizer." My system only utilizes a SSD on x64 W7 SP1, thus have TRIM enabled/defragmentation disabled. Has Norton been able to override the disabled defragmentation? If that is the case, Norton should warn their customers who are running SSDs. Thank you!" As you can probably infer, by default it defragments at 7:00PM (my system). I just discovered this and have disabled it but hope it hasn't been doing it since the end of May when I built this PC. Admittedly though, I can't find any evidence of any kind of SSD degradation using Kingston's monitoring tools. Response! "Hi, Norton products are aware of SSDs and do not attempt to defrag them. Stay well and surf safe Dick Win7x64 SP1 current NIS V20"
