I haven't used an Anti-Virus or Firewall in two years and haven't gotten a Virus or Trojan in that time. How is your experience with this?

I swear, your anti-virus software IS A VIRUS. TURN IT OFF. It is designed to flag everything you download as a trojan or virus and then charge you money to remove it. My computer has no anti-virus and the Firewall is permanently disabled, and I haven't gotten ANY Malware in two years, and it only costed $300 and can run StarCraft 2 on Medium settings with portrait animations enabled.
