Your issue may be related to an infection. Because you have a log posted, and because From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.
I am deleting my original post, which offered a possible solution.
Because you have a HJT log posted, you should NOT make further changes to your computer
(install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log
you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible.
