Here are a few very good free Antivirus products which are available:
Select one of these, or another of your choice. Do not install more than one antivirus program because they will conflict with each other. It is imperative that you update your antivirus software at least once a week (even more if you wish). If you do not update your antivirus software then it will not be able to catch new malware that may have come out.
Run a full system scan after installing and updating definitions, and then post a new HijackThis log.
