My computer seems to be affecterd by some sort of Backdoor Trojen.
I have scanned my computer thoroughly with Nortan Antivirus but can't seem
to detect it.

I have no idea what version of Backdoor Trojan it is but its very annoying
and Nortan Antivirus
real time monitor pops up the following message every time an application is
started.

Scan type: Realtime Protection Scan
Event: Virus Found!
Virus name: Backdoor.Trojan
File: C:\WINDOWS\System32\logndh.dll
Location: C:\WINDOWS\System32
Computer: SPRINGFI-6OR7AB
Action taken: Clean failed : Quarantine failed : Access denied
Date found: Saturday, 24 July 2004 3:49:17 PM

Can anybody shed some light on this annoying Virus and how to get rid of it?

My System is
Running windows xp
System Restore is Dissabled
"Add-aware" and "Spybot Search and Destry" have both been run and cleaned
out any findings with latest definitions.

I also tried searching for the above mentioned file "logndh.dll" but was
unable to find it.

What do other antivirus products have to say when you scan your drive
with them in Safe mode?

as you can see by my Hijack this that the last item O20 shows the infected
file (logndh.dll) yet there is nothing I can do
since the file physically doesn't exist. Maybe there are some other entries
I should delete as well?

None that I saw. I see you have antidote/SuperLite. Is it up to date?
Doesn't an updated antidote find any malware?

it origionally found some trojan stuff. I went through the hard disk and
deleted all the files related to the trojan findings.

I also did a online scan (house call) from Trend Micro and removed three
references to trojans. Now that all references and infected files have been
deleted all scanners and checkers come up negative. But the antivirus
software Nortan still reports the virus every time an application program is
executed

Just completed a full indepth scan with antidote and found a few files
infected with

TrojanSpy: Win32.Briss.G

though it was just in soime files hiding in my intewrnet cache folder. I
don't know weather that would cause Nortan AV to popup all the time.
 
It seems like the only way to get rid of the annoying backdoor computer
virus is to reformat and reload a fresh copy of windows. XP. It shits me off
that virus writers goto to such an extent that there seems no alternative
other than this. Because i've tried for days to get rid of the annoying
virus but nothing seems to work. So I am forced to delete windows and reload
the computer from scratch. I'm just not very happy about this at all.

The biggest problem with backdoor trojans, is that they enable the author to
control your computer. With that control, they can install additional malware,
that is not detected by any scanners. For example, they could install a
"customized" version of the kernel, that includes a new, completely hidden
backdoor, that cannot be detected while it's running.

The only safe option once a backdoor trojan has activated, is reformat/install.

Be sure to follow the instructions in
http://www.cablemodemhelp.com/xpsurvivalguide.pdf
BEFORE connecting the newly installed copy of XP to the net.
