The i am getting this on startup : The NTVDM has encountered an illegal instruction.

I have no idea as to why this is being displayed as soon as the desktop appears. This disappears on closing it and doesn't appear for the second time. But, it can shows up the next time I switch on my computer. This is a desktop and here is the HijackThis log:


Mod Edit: Removed HJT data, not allowed in this forum...no evidence of malware in this issue, IMO ~ Hamluis.

The program NTVDM is used on 32 bit PCs to run 16 bit programs. A game could be one if it was quite old. Without a bit more information it is difficult to say what the problem is.
You could check your startup folder to see if there are any "Old" programs trying to load and uncheck them.
(Start, Run, msconfig, Startup Tab.

Hi, if you ask me, I would start scanning the computer with the free version of Malwarebytes' Anti-Malware, to see what it finds.

That is listed on several malware forums as a back door / trojan. (Avast & Malwarebytes i believe)

msupdte, that is; you spelled it 2 diff ways !

The determination of whether a given file is a malware item...is not governed merely by spelling, since most of us make mistakes daily in such.

If you read any documentation, you will see that more important keys are the file path and size...and file extension.

What is the file extension of this file you see among your startups?

What is the detail for the file? What appears under Properties?

Post the error message...exactly as it appears on your system.

Directions for Showing All File Extensions

Start/Search...type in the filename and extension...reflected in the error message.

Once you find the file, right-click on it and select Properties. Post the data reflected on the General tab.

C:\WINDOWS\system32\msupdte.exe
The NTVDM has encountered an illegal instruction.
CS:0572 IP:01fe OP:ff bb ff ff b9 Choose 'Close' to terminate the application.

Details under properties:

Type of file : Application
Description : msupdte
Location : C:\WINDOWS\system32
Size : 152 bytes (152 bytes)
Size on disk : 4.00 KB (4,096 bytes)


Everything given as it is.....one more thing...........i use Quick Heal Total Security 2011 with an up-to-date virus database........it has an anti-malware software.......it doesn't indicate that this is a malware.......in fact doesn't find any malware............and Quick Heal suggests that this file is CLEAN.

I don't have any other malware catching program.

Hey guys,
I downloaded the free version of Malwarebytes and installed it. I ran it and it found about 115 objects that were infected. Then I commanded it to clean all. I didn't care to check whether msupdte was in the list or not. But, the problem is solved. Now the stupid thing doesn't appear anymore.

Thanking You,
Shiva

LOL...professional?

I've been a "professional" (meaning...I was paid to do so) accountant...and a "professional" (they call this "lifer" or "retired" soldier...those are the only two times in my life that word has been linked to me/my name :).

I play with computers...for fun and educaational reasons...I try to help with computer situations because...it's the only enterprise available in this world where shaared experiences and knowledge...may freely benefit others without any ulterior motivation/suspicion.

Many of the Advisors and other members of the BC Staff can be called "professional"...but I'm still an "amateur" in the true sense of the term :). I should add a note that the "professionals" here all donate their time and energy...for some, if not all, of the same reasons that I do...just trying to help, when possible.
