Just a quickie... You have installed HJT,only use the program with guidance.Its a powerful program and if used incorrectly can render your computer unbootable.Most of the HJT scan results are in fact needed....use with caution !!
You really should add an antispyware program or two ,such as Superantispyware and Malwarebytes
Superantispyware free click here
