It won't generate a "real log" unless something was found and removed.
Did you remove the programs I noted earlier? Are you still having the problems noted in your first post?

How many "shared files" do you have stored on there? Are all the games paid games or did you get them via P2P? This is the reason for your problems, without a doubt. It is absolutely the easiest way to get an infection.

Do you do any online banking or shopping? You need to contact your bank and credit card company and tell them your computer has been compromised and if possible give them an approximate date when all of this began, tell your credit card company that your card has been stolen so you will not be held liable for any charges you personally didn't make, because it obviously has since you couldn't make a purchase.
