NIS 2014 V21.0.1.3: 80-100% CPU usage during Full Scan

This applies to Windows 8 x64 Professional with dual SSD drives and no standard hard drives.  When running a Full Scan with NIS 2014, the CPU utilization stays at 80-100% during the period that the scanner is scanning drives.  This was reported during beta testing but was not corrected.  NIS 2013 on the same systems did not exhibit this high CPU useage.  With NIS 2014 scanning, there is a substantial degradation in system performance during the scan. 

I am submitting a SymNRA file through tinyurl.com/nortonupload that includes a full scan showing this high CPU usage. The ZIP file is named Unknown95e2dfc1.zip.   The tinyurl reference number is REF00180.

1) Windows 10 x64 Pro on ASUS Maximus VIII Extreme motherboard, i7-6700k CPU, 64 gbyte RipJaws DDR4 3200 RAM, Samsung 970 Pro 512 gbyte SSD + Samsung 850 Pro 512 gbyte SSD, EVGA Nvidia GeForce 980 Ti graphics (Home Built System); 2) Windows 10 x64 Pro on Dell 8700 SE desktop, Intel i7 4770 CPU, 24 gbyte RAM, Dual Samsung 850 Pro 256 gbyte SSDs, EVGA Nvidia GeForce 750 Ti graphics; 3) Windows 10 x64 Pro on Dell XPS 15 2in1 laptop/tablet, Intel i7 Kasby Lake 3.0 ghertz, 16 gigabyte ram. ASUS RT-AC68r router, 8 tbyte WD My Cloud PR2100 NAS drive, 200 mbps cable Internet, Google Chrome, MS Office 2019 (Local), Casper 10, DisplayFusion (3 Flat Panel Displays per system) Norton Security Deluxe, Malwarebytes 3, SpywareBlaster, HostsMan, Quicken, Weather Watcher Live, ThumbsPlus and many more (all latest versions).

Hi siliconman01

Is the CPU usage reporting it for one of the two cores?

It is on all cores.  And I have "fresh installed" NIS 2014 on all of my systems.

Hi siliconman01

I just thought I’d mention this, Dell provides a PC diagnostics check it’s the first pictogram on the last line of pictograms on the link below.

There is also the ability to Enter your Service Tag to get started.  When the page loads.

Seeing some insane usage myself when doing a full system scan. And that is with a i7 2600. Windows 8 Pro 64 bit. I will say this though. The scan was lighting fast compared to v20. Seriously no comprison at all. Night and day difference.
