Actually, Sophos updates their engine every month (though, they could do
it more often in cases of emergencies, but I haven't seen that happen).
You are only required to update your engine every three months, as the
auto-update process won't work after that.  It is a good idea to update
the engine as often as possible, but realistically, most people do it
on the three month schedule.

As for the auto-update process for the IDEs, we watch the mailbox that
receives their mailings that new IDEs have been put up on the web page.
Basically, when the mailbox file changes, an auto-update process kicks
off.  It has come in handy in a couple instances, such as the Sobig-E
virus.  As soon as the update process downloaded the IDE for it, we
were getting notifications that the virus was being caught... I am sure
a few made it to some user's mailboxes before they made an IDE for it.
