A pc with Win98 and PC-Cillin antivirus started playing up last week. Whenever an executable file was run a pop-up window with following error "Could not locate ndnjqbo.exe to run Application file". Then it gives me the option of trying to locate this file. I did a search of the entire C: drive but found nothing. A search on a working Pc with Win 98 didn't find this file either. Does anyone know of a virus that can do this sort of damage?
 
mmm...it sounds like an infection by the swen.a worm,
though it could be an aftermath of another malware.
You can refer to the manual cleaning for swen.a:

Everytime windows starts an application it queries a special registry entries. For .exe files, it queries the HKEY_CLASSES_ROOT\exefile\shell\open\command\{default} in the registry. viruses modifies this entry to hijack the execution, thereby executing the virus, then the virus will execute the .exe file requested (or sometimes infects them). I think a virus did this to your system, but the virus is no loneger existing thus the system gives you that error.

But be careful in tweaking the registry, one miss and the system dies....
 
Thanks for your help enkie!

What I didn't mention in my first note is that I'd gone ahead and deleted the windows directory on the PC and reinstalled windows. When I ran the scanning utility for Swen it found two files in the backup of the windows directory. But even now with the reinstall it still doesn't feel right. Now when I try to get into the registry it says that it's locked by the Administrator.
 
Sounds like virus (again) has disabled regedit

try to make a tekst file with this and save it to your
as regini.reg
and double click it.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000000
 
Soaplover,

Just to clarify, you want me to create a file with the following entry -
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000000

and save it as regini.reg. Where did you want me to save it to? I'm guessing c:\windows\system32
 
anywhere convenient to you, it's just a one shot process. Once its done, you can delete the file.
 
save it on the desktop with the name regfix.reg
double click it makes it be read into registry fixing
the key that locks down regedit
vurrent value im sure is DisableRegistryTools"=dword:00000001

It should be a blank line between windows... blablaa and the hkey

like this:
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000000
 
Since you have windows 98 you must change the fist line:
Windows Registry Editor Version 5.00

to

REGEDIT4


Sorry assume everybody has W2K or XP
 
G'Day!

I did as instructed, the registry changes were acknowledged with a popup, but I still get the error message when I try to run regedit.

Hijack this found the above registry setting and was able to remove it. Thanks everyone.
