Help with Hijack This

Will someone please analyze my Hijack This log file? I get a "NTVDM has encountered an illegal instruction" notification when I try to install windows updates.

I have attatched it as it is too large to put into the message.

What is NTVDM?
ntvdm.exe is process that belongs to the Windows 16-bit Virtual Machine. It provides an environment for a 16-bit process to execute on a 32-bit platform. This program is important for the stable and secure running of your computer and should not be terminated.

Please ignore the log and read the possibilities on THIS MICROSOFT (http://support.microsoft.com/search/default.aspx?catalog=LCID%3D1033&1033comm=1&spid=1173&query=NTVDM&pwt=false&title=false&kt=ALL&mdt=0&res=20&ast=1&ast=2&ast=3&ast=4&ast=8&ast=9&mode=a&adv=1) search site first.
