I've been running Norton 360 for almost a year now on my HP laptop after running Norton Internet Security for the previous 2 years on my desktop, and I keep having the same frustrating problem with Norton 360 that makes me never want to buy another Norton product ever again (I never had this problem with Norton Internet Security). Whenever I leave my laptop idle for more than 10 minutes or so, Norton 360 begins to run a comprehensive background scan, even though I have set my background scans to manual mode, and everytime the scan starts running, my laptop begins to freeze and I am unable to do other tasks. If I try to stop the scan after it has started, my laptop will be unresponsive and freeze. I use my laptop a lot for rendering purposes, and if anyone knows about rendering programs, one rendering could take anywhere from 5 minutes to 5 hours to complete, depending on the amount of materials applied, so naturally, I want to leave my laptop idle while the rendering is being completed, but can not because Norton 360 will start a comprehensive background scan if I leave my laptop idle for more than 10 minutes or so. I have unchecked the button for automatic LiveUpdate to run, and I thought that would solve my problem, but the scans are still running after my laptop is idle, so I don't know what else to do. I have tried to fix this problem for about 6 months now, but can not, so hopefully someone can tell me how to stop these automatic background scans. If there is no way to stop them, thankfully I only have 80 something days left on my subscription, so I can buy another brand computer security system that's not named Norton.
