Specs: Windows XP
My neighbor had some virus warnings appear and asked for help. We ran her anti-virus package (AVG Free Edition) and found 16 infections which it healed. Reboot was required. After reboot, received the message "WINLOGON.EXE. The application or DDL C:\Documents & Settings\Network Service\Local Settings\Application Data\Windows Server\mlthnj.dll is not a valid Windows image. Please check against your installation diskette." Further, when her logon page came up and we clicked on it, it failed to open and immediately logged back out. Now, we're stuck out. Any ideas? Thanks!

Doing a google search for mlthnj.dll brings up nothing but your numerous posts about it. So either you typed it incorrectly or it's a leftover from of the infection.

I spend hours looking to fix this problem. What solved the problem? I just renamed mlthnj.dll to "1mlthnj.dll" and I now I do not see any winlogon.exe - bad image error.

The file "mlthnj.dll" was in
"c:\documents and settings\NetworkService\Local Settings\Application Data\Windows Server".

My computer was infected with Antimalware defender virus. So, I used so many tools to get rid of it. Edited registry at places. After doing all of these, my computer was still giving me XXXXXX.exe - bad image error with the "c:\documents and settings\NetworkService\Local Settings\Application Data\Windows Server\mlthnj.dll" message in the box.

Anyway, I just renamed the file and no more annoyance.

Thank you for the help. Unfortunately, by the time I got to this, it was already affecting safe mode. I couldn't get in to rename the file or much of anything else. PC repair is not my strength so I encouraged my neighbor to take it to someone who claims those skills.

When done get a free AV software application such as "Avast Free for Home" versus an AV detection application to prevent infections.

Absolutely! I use Avast and have never been let down. Thanks!

Just to clarify, AVG is no longer just an AV detection application - this applies to most AV's these days. Obviously it let something through tho and a lot of folk seem to rate AVAST higher. Unless tested against exactly the same infection process it is difficult to be 100% about which would have faired better.

I think it's a pity more XP folk don't go online via "Drop My Rights" (from MS).
It was seen as an oddity when I once suggested it on here but I am totally convinced that it is worth it. Tiny program and a special shortcut, no background resources. The only time I have to use the old IE icon is for Windows "Manual" Updates - no big deal and another shield in the armoury. See here:
