Well Im no expert but from what I can see you have SP1 still and I think you probably dont have all the Microsoft Security Updates.

3

Which is almost certainly how these type of exploits get through, also if you have MS?SUN Java Virtual Machine (JVM) installed you need to update that (only update available is SUNs as MS have discontinued JVM).

Read How did I get infected in the first place and follow Tony’s advice. He will tell you about some ways to make your computer more secure and link to some excellent free tools to help with that.
