I don't use windows, but all of these types of viruses seem to only work
if the user is running outlook. If viruses such as this are causing
heartache, use another mail reader and you will not be infected by viruses
that invade your address book. Its really a simple, clean solution.

I'm sure many are enamored with outlook, but if you use it, this is what
you get.

Freedom to choose also has its consequences :-)
