NTVDM CPU error... caused by spyware?

    I have a new PC and got my first bad cases of spyware on it this week (despite running ad-aware, spybot and spyblaster) including LOP stuff, and all sorts of data miners and things. I ran ad-aware 3 times in an hour and each time it found about 90 things! I followed various instructions in articles on this site, and downloaded various other spyware programsn, and believe i've got rid of most of it.

    However one thing keeps happening: A black Dos box appears labelled C:\, and the error message appears:
    "C:\Docume~1\Liz\locals~1\Temp\******.exe
    The NTVDM CPU has encountered an illegal instruction
    CS: **** IP: ** ** ** ** **
    Chose close to terminate the application."

    The * symbols represent numbers and letters that seem to change all the time. there are options: Close and Ignore. Closing it makes it dissappear, only to return an hour or so later. Ignore makes another message appear with different numbers where the stars are.

    This problem has only happened since I had this spyware this week.

    I'm running XP, and downloaded SP2 the about a week ago - so much for improved security - More adware since I installed than before!

    Hope someone can help. thanks,

    Liz

    oh yeh, i forgot to say I use mozilla as a browser as often as possible (except for windows update) however i think some freinds have been using IE on my pc.

    IE now has this LOP toolbar, and I can't get rid of it. I found an unistaller for it, which worked, only it keeps coming back. anyone have a good way of getting rid of it? i have all the recommended programs on the sticky posts.

    cheers

    You should read the tutorial in this Sticky thread NO HIJACK THIS LOG FILES BEFORE READING THIS: HJT Tutorial & LOG File Posting

    Now post a HijackThis as a .txt file attachment to your message. All running programs should be closed, including your web browser, e-mail, items in the tray, anything you can close... Close before running Hijack This!

    Do NOT run Hijack This from the Desktop, a temp folder or choose run it directly from the downloaded ZIP file. Place it in its own folder, for example C:\Program Files\HJT

    First, uninstall Messenger Plus! 3 using Add/Remove programs. It is where some of your problems (including LOP) came from.

    Please follow all the steps in this Sticky thread < READ ME FIRST BEFORE ASKING FOR SUPPORT: Basic Spyware, Trojan And Virus Removal >

    Your did not follow those steps yet. There are no signs of any of the online scans having been run and I don't know whatelse you may have skipped. In addition if you followed all the steps in that thread you would not have the wrong version of HJT.

    Please read the guidelines on HJT posting again and get the proper version of HJT from the link we gave you in the READ ME FIRST tutorial. You must remember All running programs should be closed, including your web browser, e-mail, items in the tray, anything you can close... Close before running Hijack This!

    Okok, it doesn't take much to be friendly does it?

    I hadn't done online virus scans as I had done offline ones using virus software already. Sorry.

    I had only just downloaded what was labelled the latest version of Hyjack This from another website when I visited this one, so did not follow the link to download it here, assuming I had the right one. Sorry again.

    I ran the online checks, nothing was found. Also ran all of the ad-software in safe mode again, and still nothing was found.

    Unistalling Plus worked to get rid of LOP, thankyou. I've attached a new Hyjack This log from today. I have noticed the first entry in the HT log, the IE web address is obviously not correct. I had HT fix this.

    I still get this NTVDM error though. Do you know what this error is?

    Thanks for your help

    Liz, You ran HJT from

    C:\Documents and Settings\Liz\My Documents\Programs\HT\HijackThis.exe

    which is a folder for documents, not programs. Please place HJT into its own folder. Ex: C:\Program Files\HJT\Hijackthis.exe

    Post a new log once you've done so.

    After doing what Kodo suggested.

    Answer a few questions:

    1) Is the R1 line below what you fixed? Is this log from after or before fixing. If after, is it still fixed?
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://www.ywffwgzzmwsxycqypnls.com/z8CvLH5pM_0zPaAYhqeqXDScNuMN_BUqya7KLWRk11e3qTDlkPl4AfActBvNppHU.htm

    2) Is www.tiny.com your expected start page?

    3) Due you now what SupaDial is? Is this some kind of internet access program you installed?
    O4 - HKLM\..\Run: [SupaDial] C:\Program Files\SupaDial\SupaDial.exe /A

    Thanks for your replies -

    I've run HT again in program files. No, the wierd start page did not come back when I ran the scan again. And Tiny.com is my IE home page (I never changed it from when I got the pc). Supadial is ok, its the internet provider software that Tiny install on all their computers to try to get you to go with them for internet. They also make it hard to uninstall (I've removed it from add/remove programs already)!

    The links you gave about the NTVDM thing, they seem to refer to NT or 2000 computers, I'm running XP - would the same advice still apply? The error message hasn't occured since this morning actually (previously it had been happening every hour or so). And It's never happened in safe mode.

    Thanks guys

    Liz

    Your HJT log is clean. If the problem is no longer happening, perhaps you have it fixed.

    I did notice that those links refer to NT & Win2k. XP should be the same.

    Post another HJT log. I want to see if anything has reappeared. I'm not sure if this is a malware issue though.

    NTVDM will show up when wowexec is invoked. This is almost always by a 16 bit program that needs to be emulated with windows on windows (WOW). Something is being loaded that is 16 bit and NTVDM WILL chew up 100% of your CPU. What you need to do is set any programs short cut up to use low cpu affinity.

    in the shortcut target



    dfds
    cmd /c start /low [programname.exe]

    with out the brackets around the program name.
