    I read an article in the Guardian today about bots and fire walls. It said
    that if you have a router with a firewall you can block outgoing traffic on
    port 25 to see if anything keeps trying to go out (spams). I have a Bt
    Voyager router and no idea about anything that it has or has not capablity

    Zone Alarm IIRC will tell you when an application attempts to access

    Internet, it asks you to allow or block it).

    Outhouse detecting a torjan?

    Talk about the pot calling the kettle black..

  8. That always struck me as a rather useless function anyway, since many
    trojans have their own SMTP engine.

  9. Exactly. All modern ones do. The days of a trojan or other malware using
    the owner's email client were over quite some time ago.
