NTVDM CPU has encountered and illegal instruction

Hi! I recently got this error message.
C:\Windows\System32\svchost.exe  
NTVDM CPU has encountered and illegal instruction. Choose 'Close' to exit the program.

 It pops up with a MS-dos window once in a while. I've run CCleaner and ADaware without any help. Please find attached the Hijackthis log and Screenshot of error message
Any suggestions? Thanks in advance for your help.
