Hi John,
The motivation behind viruses these days is generally to steal your data
or hijack your computer for a botnet, so the odds of a virus being
responsible for disk damage are very low. Besides that, there aren't
currently any known unpatched threats for Mac OS X, and all the ones
that have come along in the last couple of years have relied on
convincing users to install "anti-virus" software or at least enter
their password to do something that shouldn't require a password. These
things are at least a little out of the ordinary.
The problem with B-Tree errors is that they can exist without actually
causing problems if you are not accessing the files they refer to. If
you don't check the health of your disk you might not notice, but the
errors can gradually become worse until they finally trash a file that
is really important, by which time the damage may have become unrecoverable.
