If a clean reinstall doesn't help it's always possible that your Norton real-time protection is 'waking up' to monitor some process it doesn't fully trust or some process that's causing a real-time conflict with Norton. Instructions are posted in cali grl's thread Norton Security Scan is AWOL.

If your high CPU consumption by nortonsecurity.exe occurs outside of system idles while you're working on your computer that type of problem can often be solved with a clean reinstall of your Norton product. Settings | Administrative Settings | Norton Community Watch.Settings | Administrative Settings | Idle Time Optimizer (an idletime defrag).Settings | Task Scheduling | Automatic Tasks | Disk Optimization (a scheduled defrag).I had an older legacy version of Norton Security Deluxe v22.15.2 on my Vista SP2 computer so these task settings might be in a slightly different location in your Norton Security v22.20.5: The Norton Community Watch task that sends data telemetry back to Norton for analysis can also consume high amounts of system resources.

For example, Norton has two disk defragmentation (optimization) tasks, and many Norton users disable these tasks and let Windows automatically handle disk optimization. There are several background tasks that can be disabled without affecting your Norton real-time protection if they appear to be consuming high amounts of CPU. With any luck you might be able to match the Last Run time of a background Norton task with a yellow peak of nortonsecurity.exe CPU consumption in your Performance Graph. Be sure to look for any tasks with a long Duration time as shown in m333617's thread Nortonsecurity.exe Running at High CPU for Long Time or tasks that run outside system idles as shown below. Note that tasks with a status of Canceled means a background task started during a system idle but was temporarily paused when your system came out of idle and will resume during the next system idle.

Then go to Settings | Administrative Settings | Background Tasks | Configure and leave that Window open to monitor the run times and duration of your background idletime Norton tasks like Automatic LiveUpdates, Norton Community Watch, etc. The default time period for this graph is 90 min but you can zoom out the view to see up to 1 month of past activity. I don't use Norton on my WIn 10 machine but if you're still looking for a solution you can monitor the CPU consumed by nortonsecurity.exe in your Performance Graph (Performance | Graph | Usage | CPU tab - yellow peaks of CPU activity are for Norton processes blue peaks are for non-Norton processes as shown below).
