Ytxsxqew.exe has stopped working

turn it off in startup .
clik your start run
type msconfig
look in top right for startups
unchek
SoftwareUpdater.exe apply close restart system

Assuming that once it starts everything is OK and the computer functions normally, try this:
Right above the start ball, there is a command line. In that white space, type MSCONFIG.
When the window opens, click on the startup tab. Find the KBD.EXE command and uncheck the box next to it. This will tell it not to run.
Now restart the computer. In Vista you'll get a message that a program was blocked. Tell it to run the blocked program. When it opens (the system configuration utility), check the little box that says not to display it again. Now everything should work.

TRY USING A PROGRAM CALLED ERROR REPAIR .IT SHOULD
SOLVE THIS PROBLEM.

First, Uninstall your program using Add/Remove Program in Control Panel.

Start Menu -> Control Panel -> Add/Remove Programs

Note: Be aware of shared files don't remove them, it will affect other programs that use that file

After Uninstall, restart your computer

Then start again, proceed to installation of your program.

Sounds like spyware / malware i would use an online scanner like Eset or a program like Malwarebytes.

also to stop the computer from restarting open the command prompt window (start menu, click run, type cmd, click ok...) type "shutdown.exe /a" without the "" and there is a space between exe and /a this will abort the shutdown.

I took this from another web site:
Michael Chiew said:
What did you do before this happened? What were your last deeds on the machine before the pop-up appeared?

I think what you're referring to is NTVDM CPU, not NTDVM CPU. Am I correct?

What do you know about 16-bit and 32-bit applications? Well, 16-bit applications are those that must work within the DOS (Disk Operating System) environment, a real-mode arena. NTVDM stands for NT Virtual Dos Machine.

In Windows XP, as in Windows 2000, or Windows 98, there are 16-bit and 32-bit environments (real mode and protected mode respectively).

Windows XP can only operate in 32-bit mode. All 16-bit applications must work within its own theatre of operation, typically, the first MB of physical memory (ram). Conversely, 32-bit applications must function above the first MB memory line. If either of these applications happens to slip into "alien" territory, you get an error message like "something" has encounter an illegal instruction. In other words, the wayward application is trying to slip by the immigration checkpoint.

In your case, updatemgr.exe (I suspect updatemgr.exe is a 32-bit application) has in all likelihood wondered into the 16-bit arena. Hence, NTVDM CPU issues that warning. 

Why do you continue to get the message. It's because updatemgr.exe incessantly misbehaves itself on start-up, always trying to load itself into a particular memory address where it is not welcome. Why the persistence? Updatemgr.exe has gone bonkers. It is either corrupted or damaged.

On the other hand, one cannot discount the possibility that NTVDM (NTVDM.EXE) is corrupted or damaged. So your problem lies with either updatemgr.exe or NTVDM.EXE, or both.

There are 2 things you could do.

First, establish who owns updatemgr.exe, Microsoft or some third-party owner. Second, rename updatemgr.exe and see whether the message goes away.

To establish ownership (and the function of updatemgr.exe), do a search for the file. 

Click START, select FIND. In the FIND dialog box, type: updatemgr.exe. See the directory in which the file has lodged. In Windows Explorer, get to the file, right-click on it, select PROPERTIES. Who owns it? Is there an indication of its function.

Next, rename the file. Right-click it, select RENAME and rename it to, say, updatemgr.old. RESTART your computer. Do you still get the error message. Not likely.

To clean things up a bit, perhaps it is a good idea for you to replace the current NTVDM.EXE with a new copy. Find out where NTVDM.EXE is. Then, click START, select RUN. Type in the RUN dialog box SFC to run the System File Checker. Insert your OS CD, follow the prompts, extract a copy of NTVDM.EXE and send it to its place of residence. Of course, you should also replace a copy of updatemgr.exe.

That should eliminate your problem for good.

Download and run this:

BTW...it's a virus you have. It will get worse if you don't clean it or restore your computer.

The file bcmwltry.exe is the tray bar process for the Broadcom Corporation Wireless Network software.

You can try eliminating the program from start up.
Click on Start >>Run, type "msconfig" (without the quotes), then click on OK.

When the System Configuration Utility loads, click on the "Start Up" tab, then scroll down to the "bcmwlt.exe" entry and UNCHECK the box next to it.

Click on Apply, then OK, and the computer will need to be restarted. Do it. Upon restart, you'll see a System Configuration Utility warning. Simply choose the option to stop it from repeatedly opening.

This will be fixing your problem
Have a great day!
