When I start up windows xp, after a few minutes an error -
The NTVDM has encountered an illegal instruction appears with
c:\windows\cda63.exe

The MS dos box appears with nothing in it. It keeps appearing for about 100
times then it happens again with
c:\windows\ec170.exe

How can I stop this at start up
Thank you

Thanks nass
I did what you said in your post and I ran the windows defender and found
nothing
I have noticed a list of mel.bat files along with other files like
26B43.exe.exeStartup in the start up menu, when i turned them off the problem
stopped. I have tracked them down to c:\WINDOWS\pss folder, I wonder is this
where the problem originates from?
