Just so I'm sure David,
If the Rootkit scan detects something it means the process is actually active at that time? You're right, SmitfraudFix was not running when avast popped up with the alert.
What I did for now is rename the file, 'Process.exe' to 'Process.xxx' so it won't run. Then... I ran smitfraudfix. The program still runs fine. But... if I understand correctly, the file 'Process.exe' only runs if it needs to stop a suspicious process. Since Smitfraudfix finds nothing, it may not need it. But... there is a file 'Process.exe' in the 'Smitfraud folder' which may be the correct one. Not sure.
At my next boot and if avast finds another file as suspect, should I delete it then? The recommended action was to 'ignore'.
Thanks.

Had a thought...
I use LiveState Recovery to backup my HDD each week and keep 3 weeks worth of backups (complete image of my 'C' drive). I looked in my backup images 3 weeks ago and see that the file, 'Process.exe' was there on Nov 29, 2008. So this file has been there awhile... not new.
