Norton Security Performance Concerns

Good afternoon.

My question relates to Norton startup processing on a Windows 10 PC (all updates installed).

I have noticed that a PC restart (and to a lesser extent a normal start with FastBoot enabled) has become extremely resource-intensive (Disk & CPU) to the point that the machine is virtually unusable for 20-30 minutes. I have switched off pretty much everything (including auto-protect) but the Norton process still appears to be consuming resources at an alarming rate. Process Explorer currently reports I/O Read Bytes at 15.6 GB. Task Manager confirms resource utilisation.

Can anyone advise on a workable procedure to hane control back to me in a more timely fashion?

Thanks
S

Hello Sal. Just so we are on the same page, have you disabled fast startup, booted then manually ran live updates until no more avaiable. Rebooted a second time to check for changes in the boot time? What do you have your boot time scan setting set at in your Norton product settings? Another question is do you have an SSD as your boot drive? 

Cheers

Good afternoon.

No, I certainly haven't disable Fast Startup. Why should I?? I also use SysMain (aka Superfetch).

I keep Norton up to date and have noticed many patches being applied. Surely the product should only be
patched, perhaps semi-annually? Of course, it's reasonable to deliver critical patches, but, in my view, high
patch frequency might imply inadequate systems testing.

Boot time scan switched off.

SATA II boot drive.

Resources have continued to increase. Norton has actually consumed more CPU time than PID 4 (OS Kernel).

I/O Read Byes now > 20 GB.

Thanks

Re: Norton Security Performance Concerns

Good afternoon.

I have uninstalled Norton and reverted to WIndows Defender. I did this with some reluctance but my options
were rather limited. It was clear to me that Norton was performing excessive processing despite the fact that
I'd switched pretty much every feature off &/or to manual. The very high I/O suggests that the product performs
a fairly invasive disk scan during startup, perhaps only after an OS restart. I'm on fairly old hardware so not
willing to lose Fast Startup, SysMain etc.

Thanks. Regards
Sal
