OK, apparantly another Forum already has a copy of Nail.exe so let's see about killing your infection.

Please copy the following instructions to a notepad file and save them because you won't be able to see this page.
Keep the notepad file Open
You will need to be Offline and NO IE windows open. When ready to start the fix, unplug your cat-5 wire from machine if you are on cable or a network.


    [1] Download the Pocket Killbox if you haven't already got it.
    [2] Unzip the contents of KillBox.zip to a convenient location.
    [3] Disconnect from internet and shut down all running programs
    [4] Double-click on KillBox.exe. and keep killbox Open.
    (Important to keep killbox and notepad file open)
    [4a] Use task manager to end process on all instances of explorer.exe
    Your desktop will disappear but that's normal.
    [5] Click "Replace on Reboot" and check the "Use Dummy" box.
    [6] Paste this file into the top "Full Path of File to Delete" box.
    • C:\WINNT\Nail.exe
    [7] Click the "Delete File" button which looks like a stop sign.
    [8] Click "Yes" at the Replace on Reboot prompt.
    [9] Click "No" at the Pending Operations prompt.
    [10] skip....

    [11] Click "Replace on Reboot" and check the "Use Dummy" box.
    [12] Paste this file into the top "Full Path of File to Delete" box.
    • c:\winnt\system32\huvkxo.exe <<or the new file name/location
    [13] Click the "Delete File" button which looks like a stop sign.
    [14] Click "Yes" at the Replace on Reboot prompt.
    [15] Click "Yes" at the Pending Operations prompt to restart your computer. Allow machine to reboot. Reboot manually if you need to.
    [16] Once restarted...new hijackthis log please.

Then Please Do Not reboot until I reply back.

Is it possible that nail.exe keeps regenerating the other file every time I delete it?

I will answer - yes, also on each reboot, this and the random file are checking each other all the time, not a new method as we have seen it before.

=============

For your information accross the ASAP network of forums we have at least 4 other topics like yours, you are not alone - as soon as one of you five show an answer we will use that method on all of you.

One of those was able to provide copies of the files and experts are even now taking them appart to find how they work.

You may see lots of views of this topic as the various experts check all the infections. Lots of trainees will also be looking over this and the other topics looking to see how the experts are dealing with this.

So in short with the collective network of anti-malware experts on this case it will just be a matter of time for a fix to be found.

THis is for Win2k only:

Click on Start, then Run ... type command and press "OK".

In the next box that opens, type cd\ and press "Enter". Now you'll see the C: prompt ... looks like this: C:\>

Type cd\winnt and then Enter.

Next, type nail.exe /FullRemove (make sure there is a space between nail.exe and the /) ... then Enter.

Then type exit and click Enter (this will close the command prompt window)

Now run hijackthis again, and checkmark/fix, if found:
F2 - REG:system.ini: Shell=Explorer.exe C:\WINNT\Nail.exe
O4 - HKLM\..\Run: [xvnlfe] c:\winnt\system32\laxchb.exe


Navigate to c:\winnt\system32\laxchb.exe and delete the file.
Check for, and delete if found C:\WINNT\Nail.exe

Reboot, and post a fresh log please.

Yay!

I'm actually quite enjoying this - in a strange way I'm helping other people and helping to prevent this happening to others in the future.

Do you mean cd\winnt ?

Cos it says cd\windows is an invalid directory.

Do I need to turn off Bullguard? Maybe that's blocking the file?

I suspect your 06 control panel present is blocking removal, for one thing.

Bear with me here...loading another 2k box to check something

A bit rusty on my DOS commands for 2k...but this should do it
Run hijackthis again to get the new name of the 04 line file.
Checkmark/fix the 06 line.
Turn off Bullguard.

Click on Start, then Run ... type command and press "OK".

In the next box that opens, type cd\ and press "Enter". Now you'll see the C: prompt ... looks like this: C:\>

Type dir WINNT and then Enter.
That should list the contents of the winnt folder.

Now type del C:\WINNT\Nail.exe and click Enter

Should be back at C:\>

Now type dir winnt\system32 Enter
Type del c:\winnt\system32\laxchb.exe Enter <<Type the name of the file from 04 line in hijackthis earlier

Run hijackthis, checkmark/fix the two lines if they are there, and reboot.
New log please.

or try this instead

Copy this quote dox to notepad - save as killnail.bat (as type all files) to the desktop

Change the lexchb.exe in the two lines below to the name of the file from 04 line in hijackthis earlier

cd\
CD WINNT
dir C:\WINNT\Nail.exe
del C:\WINNT\Nail.exe
CD winnt\system32
dir c:\WINNT\system32\lexchb.exe
del c:\winnt\system32\laxchb.exe
pause


Now double click that new icon for killnail.exe which is now on your desktop.

It will leave a DOS window open, you should be able to use the menu from that window (alt/space) to be able to copy paste the text for us.

Run hijackthis, checkmark/fix the two lines if they are there, and reboot.
New log please.
