Full scan=extremely high cpu usage

Most likely a bug. My system is no beast but it is also no slouch. Just doing a full system scan while doing nothing else. This is with Windows 8.1 with latest updates btw. I seen as much as 71% cpu usage! It mostly stayed around 50% or slightly more. I was also seeing ram usage shoot up. At one time using 3.1 gb. Anyone else seeing this? Try a full scan if you have not and see how it goes.

System

i7 2600

8gb 1333 ram

evga 2gb superclocked gtx 660

160gb intel 320 ssd

500gb sata III hdd

Re: Full scan=extremely high cpu usage

I never scan while doing anything else so my results do not mean much.Memory usage never went beyond 2.5gb,but CPU usage at times peaked at 99% and in general ran most of the time in the 20- most 40ish range.I'm sure things will be optimized over time.Personally I do not have a problem with the results as I am never doing anything when I scan.Most bugs in security software I have used over the years tend to get squashed after release as betas can only do so much.

my System is a 1st gen core i5 650

8gb 1333 ram

2 Gb ATI 7850 DDE card

1TB internal sata 3 HD

Re: Full scan=extremely high cpu usage

Testing NS on my XP SP3 laptop

Single core Intel CPU @ 2 GHz & 2 GB DDR2 RAM.

Manual full system scan takes about an hour to complete, with NIS 2014, 40 minutes for the same amount of scanned files.

CPU working @ 100% most of the time, as expected, but if my 2 GB laptop can handle this without issues, then you should have no problem.

Full system scans & resource usage is not a problem, imo, with NS, there are other more severe?? problems, I'm speaking for XP, like NTB which is a catastrophe for both FF & IE8, and some "strange" exchange of network packets, performed by NS, which occurs if you leave your pc idle about 4-5 mins after the idle quick scan has completed. In other words, you should see this behavior after LU installs a new set of Virus defs and the pc continues to be idle upon completion of the idle quick scan for the described period of time.

Re: Full scan=extremely high cpu usage

The speed is impressive. It literally scanned my whole system in like 5 minutes or so. I have another system running V21 latest version. Cpu i7 3770 and the usage does not even come close to V22. That is what leads me to believe its a bug or like you said. Needs to be more optimized.

Re: Full scan=extremely high cpu usage

I did notice some periodic cpu spikes while nothing was apparently going on between 15-30% cpu.Like I said.Things will get optimized over time.Happens with all security software.Early adopters become kind of like secondary beta testers.The system is quite snappy irregardless of the cpu spikes.
