my java is totally messed up! HELP!

My Java doesn't work, I think because of old Spyware/Viruses on my computer! I can log onto the internet, but I can't push any buttons, and there's a lot of stuff I can't see! I tried uninstalling Microsoft Java, and installed SunJava but the problem remains. I can't think of what else to do. Here is my Hijackthis log. Can someone tell me what is wrong with my computer, please????

EDIT: I'm running Windows XP
