What's in the segments file?  The virus would have existed in one of the 
attachments in another directory queued for indexing.  Those files are queued by 
a process that has no involvement with the indexing and has not caused a problem 
on another machine with Mcafee on it.  This one has F-Secure.

Unfortunately I was too quick to cancel the message as assumed it was not a 
problem until I looked at the test logs.

Yes, I've disabled it currently while the new test runs.  Let's see.  I'll 
re-run the test a few more times and see if I can re-create the problem.

Thanks for the rapid response Mike
