Norton Excessive Disk Usage Solutions

Some users have asked how to solve Norton excessive disk usage.

Task manager is showing me that norton is using an excessive amount of the disk (about 87 mb/s) at all times. This is slowing down most of my application startup times including the windows file explorer application. ... -- maxtish
The disk is constantly pegged at 1.0 to 1.9 mb/s and its Norton.exe every time. No matter what you do it will not stop including silent mode, disable auto protect, disable firewall, running a full screen game or even shutting down Norton via windows task manager (which does nothing to stop it). ... -- Zam58

Here's what worked for me.

  • After Norton installed updates, it toggled on options that caused a full scan scam and disk optimization conniption.
  • To stop the full scan, I opened Settings > Administrative Settings > Background Tasks. From the list of tasks, click anything that is running.
  • To stop the disk optimization, I went through all the settings and disabled everything else. smiley
  • I use Norton to scan downloads. Don't download anything risky? Don't need to scan your entire boot drive every day!
  • I have an SSD. Please, Norton, don't try to defragment my SSD! sad
