i believe the Run-Time errors are caused by either a virus, memory issues or some sort of software conflict, so you need to figure out what you have installed lately and back track your pc usage etc.
go with a CMS, e.g wordpress.org its your best bet, then just search for free themes for your wordperss, or edit the theme to your liking, e.g logo, colors etc.
hope that helps, thats as simple as it gets
i dont see any threats but i do see your using IE, which is a nono, stick with firefox, also you have lots of junk loading which slows down your PC greatly, they need to be removed via Hijackthis
also try using AVG or MSE for your virus app,
