After seeing all the viruses, trojan horses, worms and Reply
mails from stupidly-configured anti-virus software that's been
hurled upon the internet since 1998, and the time/money that is
spent protecting against said viruses, trojan horses & worms, I
can only conclude that Microsoft is dangerous to the internet and
American commerce, and it's software should be banned.
