LuCallbackProxy.exe & svchost.exe - again!

Tech-Archive recommends: Speed Up your PC by fixing your registry


I've had horrendous problems with LuCallbackProxy.exe last couple of
weeks.

I e-mailed Symantec (Norton) for advice and help. They just been
e-mailing back that they will get back to me. Yeah, right.

I gather that the file is _supposed_ to be Norton?s process residing as
a hidden file in C:\Program Files\Symantec\LiveUpdate. It has a brethren
LUCALLBACKPROXY.EXE-29128DB6.pf in C\WINDOWS\prefetch. It?s supposedly
used by the Norton suite of programs to update virus and software
definitions.

I have an XP SP2 machine hooked up to the Internet by 3 Megabit DSL
modem. Whenever I turn the modem on, in short time the
LuCallbackProxy.exe spawns itself into 3 to 5 copies and eats up 100%
of my CPU resources. This may go on for a few to tens of minutes. Then
the processes disappear and I can do work again since CPU usage drops
down to the normal baseline of 5 to 15%. But 5 to 30 minutes later we
are back to square one. Deleting the processes manually using the
Windows Task Explorer works, but only temporarily.

I wanted to know if I am dealing with the real Norton?s
LouCallbackProxy.exe with perhaps a back door exploited by a hacker or
with rogue software pretending to be LouCallbackProxy.exe and hiding
somewhere inaccessible in the bowels of the Windows directory. So I
temporarily renamed the files and waited to see what would happen.
Nothing, not for a long while. So the back door is plausible. Or at
least the hacker couldn?t find the files he was looking for.

But in a day or so a new problem popped up. svchost.exe popped up and
started to devour 100% of my CPU time.

Any ideas on how to diagnose this problem further?

There has to be a hole in my security, though both the Microsoft
Firewall and the Norton Internet Security suite report everything just
honky dory.

Thanks for any ideas.
