Windows 7: 16 bit MS-DOS Subsystem pop-up

16 bit MS-DOS Subsystem pop-up

Well today I was putting in Windows 7 Home Premium in my 2nd hard drive. Been setting things up, adobe flash player, install firefox, etc. but when I left my room and I come back, I got this weird cmd.exe in my background but showed up with a pop up saying this...

Title bar: 16 bit MS-DOS Subsystem

"C:\Windows\system32\cmd.exe
The NTVDM CPU has encountered an illegal instruction.
CS:0de8 IP:011d OP:65 2e 63 6f 6d Choose 'Close' to terminate the application."

So I click Close. Nothing seems to happen... but what I remember, I was using the Yahoo! CA Anti-Spy program and allowed the hijacker but I thought it was a false positive... it something like start.jk.swa or something I can't remember at all. So there it went, then I got that message above in the quotation. Well I went back to the program, and look in the allowed windows, and remove it. Then I try to rescan it again, it never come back up. :/ Oh well, hope nothing happens.

My cousin helped me to search... I type in the whole thing in google, nothing shows up but he found this...

...and its saying like I might have malware instructed. it also said something about win. xp, and nope I don't have win xp anywhere. No program are set as xp compatibility. So, any idea anyone?

Btw, it popped back up again, so idk if it would be continuous.

So my cousin told me that I can't run 16-bit program on win. 7. That... make me think of PhotoShop3, they use a 16-bit mode. I remember using it in the Win. 7 R.C. Beta mode, no problem, even tho the 16-bit does shows up in the task manager.

-Edited-
I restarted my computer, I don't see it come back up again. Might be some application or program that got hung up. But if i seen it pop up again, I will let you all know.

I just already did that, no result. Pretty much it might been an application or a program got hung up and after I restart, there was no problem.

Okay ... well clean your Java cache too ... This application will safely clean it. It works with Windows 7 even tho' it doesn't say it does.

I'm good, I have ccleaner and fcleaner, Avast Anti-virus, malwarebytes' anti-malware, and Yahoo! CA anti-spy. Those should be good enough.

Basically there might be a program or an application got hung so yeah. Just 1 restart, its fixed. Weird error tho... freaks me out LOL.

You definitely have a virus with this file

Go to Strut > Run,. and type msconfig,. click the Startup tab and uncheck everything except your anti-virus.

However, It nay be running in the registry also.

Well, Mr Chamberly, I think you can do something like: win+R --> services.msc --> Interactive services detection --> Properties and you set to "Disabled". Thanks!
