"…We Don’t Need No Stinking Security Software. Security software is a scam. A rip-off. A waste of money, a pain in the neck, and a surefire way to bring even the speediest PC to a crawl. Half the time it seems to cause more problems than it solves. Oh, and one more thing: It’s unnecessary.
Heresy? Crazy talk? Recipe for disaster? No, no, and no. For the past several years, I’ve run Windows (first XP, and now Vista) without a single byte of third-party security software. No ZoneAlarm. No Norton Internet Security. No Spyware Doctor. Not even freebie favorite Avast Home Edition. I use nothing but the tools built into Windows and a few tricks I’ve learned." – Content courtesy of Security Software: Protection or Extortion?
