Here it goes,

I've encountered some sort of pop-up spyware, only thing I could find was that it generated a random(I know because when I got rid of one, a new one with different name would pop up) exe file in Windows/System32,

Spybot and Adaware don't find it, not found by CWShredder,

File Created is: C:\Windows\System32\ahkiuur.exe (though I really think the name is randomly generated)

Anyway, I deleted the file on another user account since I couldn't on mine(gave me some sort of in use bs), and replaced it with a bogus file I created with notepad under the same name. (which has helped me deal with these programs before)

Now I don't get pop-ups, but get the following error window:

Heading: "16 bit MS-DOS Subsystem"

Text: "The NTVDM CPU has encountered an illegal instruction. CS: 0557 IP: 0009 OP: f0 de 01 1A 04 Choose 'Close' to terminate application."

I can close the window, but everytime I go to a new page I get the error repeated.

There is also an ignore button: What will clicking it do?

I think I am on the right track since none of the commercial apps can find it, but I was wondering if some one here could help. If I am screwing with the wrong thing, please let me know,

Any help would be greatly appreciated!

Here is my hijack this log:
