My computer scares me...

It's really strange to wake up in the morning and stumble to the computer to read the news and find your computer has a mind of it's own. I looked at the screen and it seems that overnight, it had downloaded updates, restarted itself and was ready for me to log in. And it put up a firewall so I couldn't get on the internet and since I rely on my oldest to keep me in the computer world and he's thousands of miles away, I was stuck. But, I'm smarter then the computer (I think). I turned the firewall off. Was that a mistake? Yikes! Maybe if I named my computer and fed it something besides little bits of pizza and splashes of wine it would be nicer to me!
