Memory and CPU Usage problems after uninstalling NAV

Although this may appear to be off-topic, I feel sure that it is related
to the use of antivirus software and I hope that someone knowledgeable
can suggest a solution. I apologise for the length.

I am running Win98SE on a system with 512MB of RAM. Until recently I was
using Norton Antivirus 2004. When I received the error message "NAV has
encountered an internal error. Please uninstall and reinstall NAV" I
decided to replace NAV with another program, because this had also
happened a year or so ago and twice was once too many for me. Uninstall
appeared to be uneventful and I manually deleted the few files left in
the Symantec common user etc folders. I then installed a trial version
of Kaspersky. This performed a scan of my hard drive and no viruses were
found. (Neither had NAV found anything in regular weekly scans). After
about 4 or 5 hours I found that my mail client could no longer connect
to the server, and my browser was unable to resolve DNS addresses. A
reboot put things right for another 4 or 5 hours, then the problem
resurfaced. Thinking that there was maybe something wrong with my
installation of Kaspersky I uninstalled it and ran without any
connectivity problems at all for 48 hours continuously. I then loaded a
trial version of F-Prot and found that the connectivity problems had
returned - a reboot is needed every 4 or 5 hours. F-Prot had also found
no viruses after a full scan; I have also used Adaware and Spybot, with
the latest definitions, and nothing was found.

AIDA 32, and a memory utility, both show that memory gradually gets used
up after every reboot; when down to about 30 or 35% free, i.e. after a
few hours, I cannot connect to web or mail servers. Also, no doubt
significant, CPU usage reaches 100% and stays there within a few seconds
of rebooting. It looks like there's an internal struggle going on which
is gobbling up resources, but only when an antivirus program is running.
I suspect that something left behind by Norton, presumably in the
Registry, is causing the problem.

If anyone can suggest a solution I would be most grateful!
 
Have you obtained Symantec's NAV removal tool to completely remove the product ?

Thank you for the suggestion.

There doesn't seem to be one for NAV2004, only for 2003. Of course, I
may have missed it; navigating the support site sometimes takes you back
to where you started!
 
I have set follow-up posts to; symantec.support.winnt.nortonantivirus.general

Maybe you can get direct information there.
