After updating the virus definitions (7/21/04 update) IE is running slow if Norton auto protect is left on. I'm using NAV 2003. Anyone else having problems. Symantec is not much help. If auto protect is disabled IE runs fine.

This looks like a classic interaction between IE add-ons and a real-time scanner: with Auto‑Protect on the SYSTEM process spikes when IE runs (as reported). Rather than immediately removing software, the next step is to isolate which layer (IE add-on, user‑mode service, or kernel/driver) is triggering the scan.

  • Start IE with add‑ons disabled (iexplore.exe -extoff). If IE is normal, the problem is a browser helper object or plug‑in. Use IE’s Manage Add‑ons and re‑enable items one at a time to find the offender.
  • Perform a clean boot (run msconfig, disable non‑Microsoft services/startups, reboot). If the slowdown vanishes, re-enable items in small groups to identify the conflicting service.
  • Test in Safe Mode with Networking. Persistence of the problem there points to a driver/kernel component rather than a regular add‑on.
  • When SYSTEM goes high, capture which module is responsible (Task Manager → more details, or better, Process Explorer to inspect the SYSTEM threads and loaded drivers). Note exact driver/service names for diagnostics.

If Auto‑Protect is the culprit, try configuration changes instead of immediate uninstall: narrow real‑time scan scope (exclude browser cache/temporary folders or iexplore.exe where the AV UI allows it), and temporarily disable any “scan web traffic / scan downloaded files” option while testing. Collect targeted logs before making big changes — Windows Event Viewer entries, a short Process Monitor trace of the moment the spike occurs, and the Process Explorer snapshot — and supply those to Symantec support so the vendor can reproduce and patch the regression.

This approach keeps the system protected while pinpointing the root cause. It complements earlier suggestions about updates and alternatives from and by focusing on concrete, non‑destructive diagnostics and the specific artifacts support teams will need.

New updates installed today. Same result. Whenever I run IE, SYSTEM on Windows Task Manager jumps up to 40 - 50% when auto protect is active. It only goes up to 5% when auto protect is inactive. I've run Spybot S&D and AdAware. A Norton virus scan shows nothing. Any suggestions??? Thanks in advance for any help.

Go to the Security Section of this fourm create a new thread and post a hiojackthis log .Please dont post it here ,Download hijack .

Download 'Hijack This!'.HERE
Download link is on the left

Unzip (extract) it to a folder of its own.Like c:\HJT\hijackthis.exe , Then Doubleclick HijackThis.exe (in the new folder), and hit "Scan".
When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, then Ctrl-A to Select All, and copy its contents here. for hijackthis,most of what it lists will be harmless or even essential, don't fix anything yet.
Please close all Open windows programs and Browser windows before you run hijackthis .

I would suggest running 'LiveUpdate' again for Norton. Keep running it until all program component updates are downloaded, and you get the "Thank you for using LiveUpdate' message.

But even more i'd recommend you dump Norton products from your system and start using better alternatives. If you have Norton Internet Security running as well as Norton AntiVirus, I'd suggest you dump that one as a matter of urgency!

Norton products are about the slowest and most resource hungry alternative available, and performance problems have plagued their use year after year!

Catweazle, any suggestions for a good anti-virus program?
Caperjack, will do. Thank you both.

I would personally recommend NOD32 for personal use and Sophos for corporate use. Neither are free!

I second the comments on Norton. I persevered for about a year until I got tired of reinstalling because of corrupted updates etc. Used up to 70-80Mb of memory whilst surfing. I now use EZtrust AV & sygate Pro firewall. Got EZ with the Microsoft update CD. It works well. There is a free for one year deal at the moment on it.

As i surf right now ,navapsvc.exe is using 1120k of mem .
I have to admit that every now and then i get a update that serews a little ,but t he next ones always fixed it .I have had the best luck with nortons over the years .
I got that windows update cd last week ,was going to uninstall nortons just to try EZtrust but decided not to

When I had the problem in '04, I took everyone's advice and dumped Norton. I've been using AVG since and have had no issues.
