A couple of things spring to mind, I can see the method of stopping the "Optimize Disc" function but I'm running an SSD drive and that from everything I have read certainly doesn't want or need that.
I would have expected that Norton would have built a recognition system into the program to disable this automatically.
File cleanup is another one that wants sorting out, it certainly cleans your files but too well, every thing goes when you use it, passwords being the one thing I don't want removing goes with every thing else.
If there is a method to stop this it's not very well identified in the control panel and I would have expected to see this option.
I may have missed this option some where in the instructions but if it's not clear then people will get frustrated. The settings button is another thing that need to be more visible , please make it stand out so it's instantly identified.
Last but not least, when exploring the Norton "Performance" section 4 items spring up but if you click on any of the items it does what it says immediately, not a good idea, far getter to bring that option up in another screen then have the option of using it.
Up to now I've wiped my browsing history and passwords out twice by mistake.
