IF they are serious and are willing to put up with the inconvenience, I
recommend installing the NoScript and Flashblock Firefox extensions.
These should prevent any drive by malware installations.  NoScript also
has some XSS prevention too.  The downside is that web browsing starts
to break down when scripts are blocked across the board.  The user can
approve scripts one by one, or white list scripts from entire domains.
But training NoScript to do so is a chore.

On the plus side, blocking scripts makes browsing super fast.  And those
annoying flash banner ads never bother you.

Oh, and setup OpenDNS too.  Create a profile and block parked domains in
addition to the default phishing / adware blacklists.  I've been
noticing that some parked domains should be classified as phish but are
not.  And, nobody will really miss a parked domain.  Use DNS-o-matic to
register and auto-update your client's IP address w/ OpenDNS.
