real men don't use spyware blockers and firewalls. Like me.
And since I know someone is gonna ask this: No, I don't always get a virus, I never have to reinstall more often than you usually should (One install of windows shouldn't be left on a computer for more than 6-8 months before formatting and reinstalling), and I'm only running 28 processes currently on my deesktop, which has been running on the same windows install for 6 months now.
If you don't want viruses, don't go to questionable sites, don't download game cracks (or any programs that aren't reliable for that matter), and don't download too much porn. Simple as that.
