Hi,

maybe it would be best to download HJT from here:

http://free.antivirus.com/hijackthis/

Using HijackThis
To analyze your computer, start HijackThis and run a scan. See the Quick Start Guide for help in running a scan. HijackThis will display a list of areas on your computer that might have been changed by spyware. Do not change any settings if you are unsure of what to do. There are many popular support forums on the web that provide free technical assistance by using HijackThis log files to diagnose an infected computer.


... and then post your HJT log at ONE of the following HJT forums:
