And then the client asked me to look at his Windows XP laptop, because it's been "acting funny."
He has broadband at his house. He's never run Windows Update.
It's after 9:00 at night and I'm still here. Why am I still here? 1,524 copies of the W32/Bagle.z virus and counting. Plus about 6,000,000 Windows security updates that need to be installed. And did you know that Bagle blocks Windows Update from doing its job? Isn't that lovely?
If you are reading this on a Windows computer, and you have never run Windows Update on your computer, you are infected with a virus. Or more likely, thousands of viruses. Yes, I mean YOU. Right now, the average life expectancy of an unpatched Windows box connected to the Internet is less than twenty minutes.
I could be at game night right now. I could be hanging out with cool people and playing Are You a Werewolf? But no.
