First of all, you are using a very old version of HijackThis, please use the latest (1.99.1)
Click on the link in my signature and visit the HijackThis section.
It has everything you need (to know).

Secondly, your Windows as well as your IE are not up-to-date which leaves your system very vulnarable to infections/hacking etc.

I suggest you do not only have a look at the HJT section but also follow the instruction in the malware removal section on my website.
