Performance degradation on Windows 2000 Laptop with Norton Anti-Virus 2005

A followup to http://www.experts-exchange.com/Security/Q_21113477.html?query=performance+norton+2005&clearTAFilter=true

which points to a Symantec knowledge item that does not seem to be there anymore, and which I can't find by searching Symantec's knowledge base --

I installed Norton AntiVirus 2005 on a Windows 2000 laptop, and the degradation of performance makes the laptop unusable while it is installed.  Removing it brings the performance back to an OK level.

Two questions:
1.  Any ideas how to combat this?
2.  Is there a way to disable this and bring performance back, and then only enable it when occasionally online (I know I can stop AutoProtect in the Services list).

Thanks so much.

Also, anyone know where or what that knowledge base article is/was?

Try to uninstall Norton 2005 !!

It worked ?? If not, try to increase the Physical Memory of the machine !

You can also stop Norton Real Time Protection in the Systray Icon, by right clicking the icon, and uncheck enable Auto-protect!

But for sure, the increase of memory will solve your problems!

Thanks for the comments.

1.  Memory upgrade was done recently, to 196 MB RAM.  There are only two user apps running, Word and sometimes AOL, so the processor is not doing much work.  The repair shop does not think the memory upgrade will help.

2.  I know how to enable&disable AutoProtect, and thanks for the tip on doing it easily from the system tray.  What I want to do, however, is start/stop the entire NAV application at will, since there are other things going on at the same time as AutoProtect (for example the LiveUpdate program).  

3.  Below is a comment from the Experts-Exchange item mentioned in my original question.  What I really want to find is the information referenced in that item (and shown below).  The link is no longer pointing to a document, unfortunately.

NAV2005 as well as NAV2004 are both great AV software... but sometimes they are producing harddrive overhead. Symantec has some advices referring total performance improvements; look at:

Thanks for any additional ideas.

Microsoft has a KB article that simple says the opposite, but... the repair shop should know it !

Thanks - I wonder if you could point me to the MS KB article.  (The memory upgrade that was already done did not seem to help - but I agree with you, it seems that additional memory would fix this.)
