Hey, sorry about the delay. I got sidetracked in the middle of my day. No viruses. No spyware. You can set the refresh rate on the 'wallpaper'. The options are 1, 5, 15 and 60 minutes. They give you quite a few things that you can change. I used to use a tiled version of a gif I found here for my wallpaper. It alternated the Imp and Reb insignias 1 half at a time and had a blue lightsaber up the middle. I think J made it (but I could be wrong about that...). I dont think I'm going to stop using this though. At least not until I find something better. You DO have to be connected to the internet for the image to update.
