Just thought I would give you guys a heads up about this thing. I was on Yahoo's site a while ago and all of a sudden my browser quit working (it gave me the page cannot be displayed page whenever i clicked on links). I noticed some new links on my favorites that I didn't add, and there was some sort of screen saver program that had been installed, as well as a few new icons on my desktop. All of this happened within a few seconds and I was unable to access the internet because it gave me the page cannot be displayed thing. So I did some digging and found a thing called SahAgent that had been installed...I deleted it and all is well. Have you guys heard of this? How can I prevent it in the future?
