The log file shows nothing. What file is reported as infected and what is its location?
Also immediatly visit windows update and get/install ALL security patches/updates. both your windows and IE are not up to date.

I also see no firewall. Unless you have a router/firewall, I suggest you get one.

Also please use the latest version of HJT.

With HJT you can fix these things:
