Your problem quite likely didn't have anything to do with "powerful"
trojans at all.

This is a language file that contains french translations for application
strings.  It doesn't contain executable code so it's not a likely
candidate for an actual virus.   More likely a false report from your
virus scanner.

The classloader virus apparently only affected java versions prior
to 1.2, so if you are running with a recent version you should 
have been protected from it.  All the google references i could find to
this virus are from 1998 and 1999.

Hmmm... my guess is that your virus software will still complain about the
language file and will again complain about the classloader issue if
you revisit the offending website.  On the upside, rebuilding your system
probably fixed whatever the real problem was too!
