I think you make an important point Casper. While Linux users might feel
a bit complacent perhaps, that they are not vulnerable to virus and
other attacks we can receive and and forward mail to Widows users and
pass on infections that way. It does mean that if we want to be though
of as responsible user we should have a virus application to at least
scan our mail.
Unlike James, I do not place a lot of faith in ISPs and online services
carrying out virus protection for me, at best they filter spam with some
degree of success but cannot hope to catch much else.
While we may be safe comparatively immune from virus builders attentions
we are just as vulnerable to Phishing and Trojan infiltration as any web
user.
