Norton Anti-virus is a CPU hog???
Hi -

I noticed something today and i would like to know if it is "normal".

Background: Pentium II, 400MHz, 256MB Ram, 8 Gig HD (2 Gig free), Win2000. Norton Systemworks, including Anti-virus.

Anyway, i run the system Doctor usually (i know, it uses memory up, but the computer runs well anyway), and this morning after re-booting i noticed that the CPU Meter was constantly in the 75%- 90% range. Always. I didn't have any programs running and was not connected to the internet.

So i checked the task manager (processes) and this (navapsvc.exe) seemed to be pretty active. So i shut down Norton Antivirus and the CPU usage dropped to 5% immediately. I turned it back on, and the CPU usage went back up. And I am not doing a full system scan (that happens every friday night).

Is this normal? The computer seems to be running just fine. No viruses, no spyware. It's a little slow, but then again it's 3.5 years old and i want a new one. But all in all everything is fine.

I guess i could understand if i was downloading something (especially e-mail), but i use dial-up and was not connected to the internet.

Any suggestions or comments. Thanks.

Tom

PS - i should note that the above may have always been the case and i just never noticed so it might not be a "new" condition.

Would this question be more appropriate in the Hardware or Win2000 forums?

Hi tomlunt,
Try setting autoprotect to scan only downloaded or created files. Then set it to scan program files and documents. Now someone may have an opinion on my next suggestion but I would uncheck smart scan also. Mine runs in background and uses very lttle resources with these settings. Be sure you change these in the auto protect section. I also have my manual scan set to scan all files when I do it myself.

thanks for the tips, however, i couldn't easily find the items you mentioned, so i did what we all do when something goes wrong in windows: i uninstalled and then re-installed (Norton System works, that is). It worked.

I don't know why, but the CPU meter is back to normal (about 5% usage when nothing is going on).

I'll just chalk this one up as unexplained.

Thanks for your help.

Tom
