Norton 360 using between 50% and 100% of CPU for hours

Every time I boot up Norton is taking anywhere between 50% and 99% of CPU, and this is for hours at a time, not 30 seconds. It is becoming so bad that I have deinstalled, then reinstalled, but the same behaviour is present.

What’s the problem, has anyone else experienced this, and is there a fix apart from cancelling and completely deinstalling Norton?

System is i7, 64GB RAM, GTX 1080, 2TB SSD.

I’m wondering if your Norton is running Idle Time Optimizer (calls Windows defrag/trim)


I’ll disable Idle Time Optimizer upon Norton 360 install.
I recall comment…once it starts, it wants to finish.
No…must be something else.
any other real-time security solution

Thanks for the reply

Current version of Norton, and no disk defrag enabled - I use perfect disk for the other sata drives.

Has been an issue for over 4 months now so I have now given up, de installed and moved to bitdefender. CPU is now down to a normal 5-6 % doing the same things as I had been when Norton was driving cpu to over 80%.

Solved but not via any Norton config.

Thanks

Stop your Norton subscription from automatically renewing

Community urges users that do not want automatic renewal to cancel recurring subscription service and also remove billing information.

Same issue here, since JanuaryFebruary, some update triggegred high usage cpu for idle tasks… pretty bad experience. 7 months and counting, no fix.

Hello @AleX
OS?
Norton product & version#?

Same issue here, since JanuaryFebruary, some update triggegred high usage cpu for idle tasks… pretty bad experience. 7 months and counting, no fix.

Win11//64; Ver 22.24.7.8

and you’ve refreshed your Norton install?

I have now switched to Bit Defender - and cpu is idling at 5% - and when doing a scan, Bit Defender only takes 14% … so its now quiet and clutter free in comparison to Norton…

Is that a workaround or we are just guessing here?..
