The other day, I started experiencing some curious behavior.
Command (DOS-like) windows kept popping up and disappearing.
There would be probably about a dozen windows tiled and this happened
so quick that I couldn't read the file on the top of the window bar.

I also keep getting warnings from McAfee about the following files:
20391529641.dll
dllgh8jkd1q8.exe
kernelwind64.exe
m1ax1d12132116143v.exe
n2ewma1xxsv234.exe
newmaxxsv234.exe
vedxg4am1et2.exe
vedxg6ame4.exe
vedxga1me4t1.exe
vedxga3me2.exe
vedxga4m1et4.exe
qt-dx331.dll
gdnOT2904[1].exe
ma11x1dd121111v.game
WADA.EXE

Most of these have been associated with something called Dialer-257. Others have been associated with Generic.dx (Trojan), Generic BackDoor (Trojan), or New Malware.j (Trojan).

I also keep hearing a regular -blip- sound. This is the default sound associated with 'System Notification'. This keeps sounding at regular 50 second intervals.

This morning, I received a flash of the Command windows with the following notification:
------------------------------------------------------------------------------------------------
16 bit MS-DOS Subsystem

C:\WINDOWS\system32\M1AXD~2.exe
The NTVDM CPU has encountered an illegal instruction.
CS:0548 IP:0254 OP:63 68 61 72 73 Choose 'Close' to terminate the application.
------------------------------------------------------------------------------------------------
This keeps happening regardless of how many scans I do.
I've done AdAware, Spybot-S&D, Symantec Online, etc.

Please Help
I think something has taken over the system!
Mike
