Norton Antivirus Using Cpu

HP Laptop with Windows 8.1, Pro, 64-bit, Quad-core i7-3630QM processor, Norton 21.1.0.18 usage runs from 0 to 1. Good.

But, HP Desktop with Windows 7, Pro, Sp1, 64-bit recently upgraded to IE11, Norton 21.1.0.18 has been averaging NIS CPU 8 constant usage for the past 2 days. Opening and looking at Norton s Performance History for the past month confirms this is a new issue that started about 2 days ago on the Windows 7 Desktop.
The W7 s i7 x 980 1st Generation 6-core processor usually runs at 1.5 MHz. But with this high NIS usage, it is stuck running at 3.334 MHz.
Rebooting the W7 PC does not prevent the high NIS CPU usage.
The W7 s Task Manager shows 2 NIS.exe 32 s running, one under the user name of System, the other under the user name of Admin. A posting elsewhere in the Forum says this is normal.
So, out of curiosity, I signed on to my old HP Desktop with XP, SP3 and confirmed that Norton usage was at a relatively low level for the past weekuntil I just now signed onto that XP. Now, Norton is running at 20 constant usage on it.
To the Symantec/Norton employees who might read this thread, has there been a recent NIS update that might be bringing on this high NIS CPU usage.
One thought is that within the past couple of days, the NIS Nag Screen has popped up reminding me that there are less than 30 days on the current subscription to all 3 PCs. The high usage on 2 PCs does not prompt a person to renew unless a solution is available.
I am a lower-level techie, so I may not be able to diagnose much at deeper levels.

Early computer viruses under MS-DOS were simple things, chunks of code appended to executable COM files. Norton Antivirus was there, starting in 1990, working to wipe out these nasty infections. Norton AntiVirus 2014 continues to do the job, growing and evolving to face ever more complex types of malicious code.
Like Bitdefender, Kaspersky, and a few others, Symantec has stopped using a year or version number for its Norton product line. I ve appended 2014 for the simple purpose of distinguishing this product from earlier versions.

Big, touch-friendly buttons on the main window let you quickly launch a scan or check for updates. An info panel monitors CPU usage overall and specifically by Norton. The product comes configured for the best balance between security and performance, so most users won t need to dig into the product s settings.
A New Technique
When I met with Symantec representatives prior to this review, they explained a truly impressive new feature that s been added to the current version. Sometimes malware infests essential Windows components, in effect taking them hostage. The antivirus can t quarantine the infected file without disabling Windows. The best solution would be to replace the file with a clean copy of the original, but licensing issues prevent doing so directly.
To clean up this kind of problem, the product first consults the immense Norton Insight database to locate the corresponding clean file, then runs a cloud-based comparison against the infected edition. It supplies the local Norton installation with a file that represents the difference between the two in effect, a set of instructions for changing the corrupted file back to its clean equivalent. Once the clean file has been verified, the cleanup is complete.
I frequently run into big problems with antivirus products that get too aggressive and delete important Windows files. I m really impressed with the cleverness of this technology.
Installation Ups and Downs
The installer for Norton AntiVirus checks for problems and, when possible, solves them. For example, on one test system it detected an illegitimate proxy installation and offered to remove it. Doing so saved it from a host of post-install connection troubles.
When malware has rendered a system unbootable, or when ransomware actively blocks access to the system, the Norton Bootable Recovery Tool offers two ways to save the day. You can run Norton Power Eraser, an aggressive malware-killing tool, or run an advanced recovery scan. This tool easily wiped out ransomware on one test system, allowing installation of the full product.
On the flip side, the new cleanup technology I described didn t prevent Norton from damaging two test systems to the point they would not boot. On one system, Norton s Auto-Protect flagged a number of files immediately after installation and requested a reboot to finish cleanup. After reboot, it went into an endless logon/logoff loop. The other system couldn t update, activate, or call on its built-in support. On advice from tech support I tried Norton Power Eraser, and when that didn t help, Norton Bootable Recovery Tool. This system ended up in the same kind of logon/logoff loop.
Getting these problems fixed required several hours of interaction with tech support, including remote-access diagnostics and repair, which was rather disappointing. Both systems did eventually get fixed, but it took a lot of work. I rate the installation experience at two stars.
Oct 09, 2008 Norton AntiVirus 2009 hits all the right security notes, and its superior protection technologies might even win back some jaded anti-Symantec folks.
