Yeah, AV is a huge unknown and one of the first things I always check
myself when I'm having problems like this...
Hmmm... a side question then...
I can't imagine indexing just the headers would be very taxing - why not
only index those by default, then, whenever someone does a body search,
pop-up a box informing them that full text searches would be much faster
when the body is indexed, but warning the user that enabling them *will*
cause temporary performance issues until the indexes are finished
building. I'd think this would be a relatively easy fix, bu I've been
Also, even though you may not be able to show an accurate progress, you
could still have a very visible modeless pop-up box informing the user
that indexing is occurring, with the best effort progress bar inside it
(but don't allow the user to totally close the window, just minimize it,
until the operation is completed)...
