There are some nasty people in internet land.
I decided that rather than downloading a pre-made template I would change my layout html and then try to find a cute background. In my search, I clicked on a google search result, and ended up with a trojan horse and a virus. I had a number of things going on on my computer at that time, so it took me a while to figure out what was happening.
I cannot fathom what makes someone want to embed a virus in what appears to be an innocuous, even helpful site. I tend to be a very un-trusting internet used, so the fact that this happened to me makes me realize how easy it is for someone to get a virus.
Anyway, be careful out there.
