Good morning fellow Beepers.
I need your help.
I have windows XP.

When first logging on to my computer and to firefox I get this message:

16 bit MS-DOS Subsystem

C:\PROGRA~1\LEXMAR~\lxbbbmgr.exe
THE NTVDM CPU has encountered and Illegal instruction.
CS:054aIP:0101 OP:ff ff ff 99 ff Choose "close" to terminate the application.



I choose the close button.
Then I get:

MsnMsgr.Exe - Bad Image
The application or DLL C:\WINDOWS\system32\SensApi.dill is not valid Windows image.
Please check this against your installation diskette.


I click the ok button.
I have to click the button three times to get rid of it.

I can't get into my MSN e-mail or Windows live messenger.
When I try I get:

msmgs.exe - Application Error
this application failed to initialize properly (0xc0000005) Click on OK to terminate the application.


I tried the SpyBot but that did not work.
What happened to my computer?

lxbbbmgr.exe Is for a Lexmark printer

MsnMgr.exe

If the path to this program as shown on the Tasks tab is anything other than "C:\Program Files\MSN Messenger\msnmsgr" then you have a virus, such as the W32.Mytob@mm \ W32.Mydoom.bg@MM virus (Typical locations for this virus are "C:\Windows\System\msnmsgr" and "C:\Windows\System32\msnmsgr").

Spybot - Nothing
C Cleaner - Nothing
Ad Aware - Nothing
Avast - Nothing
Norton Antivirus - Nothing

Can't get passed that 'not a valid image' message.
Couldn't uninstall Lexmark because it reads it's in use.
I don't have my printer connected to my computer.

Anybody that can help please?

You might have a Lexmark application running at Startup. You can disable it in the System Tray or go into Safe mode and then try to uninstall

Uninstall the MSN Messenger software. Reboot and see if both error messages go away.

If the NTVDM message remains (but the MSN doesn't) then look for older programs on your system. This is most often caused by problems with a 16 bit program running (you may find it associated with wowexec.exe in Task Manager...Processes Tab) - although I've seen references to some 32 bit programs causing it also.

The System Tray (aka the Notification Area) is the area that the clock is in (in the lower right corner of the screen). It includes all those little icons that run when the system starts.

To get to Safe Mode, rapidly tap the F8 key just before the Windows Splash Screen shows up (the first time that you see the Windows stuff). As long as you start after the BIOS has finished posting (all that white text stuff that scrolls by at first).

You can also use this free tool to reboot into Safe Mode (from within Windows): http://www.superadblocker.com/bootsafe.html
Don't forget to set it for normal mode BEFORE you exit Safe Mode - otherwise it'll just bring you back to Safe Mode.
