Download the latest version of HijackThis! Link 1 Link 2
Unzip the newest version of HJT into a new dedicated folder. Very important!
Create a folder on the C: drive called C:\HJT.
You can do this by going to My Computer (Windows key+e) then double click on C:. Then right click and select New then Folder and name it HJT.
Unzip HijackThis into this folder.
Launch Hijack This. Then press Scan, and press Save Log. This will generate a text file that will list all running processes, all applications that are loaded automatically when you start Windows, and more.
Caution: Most list items in the HJT log are harmless and needed so don't make any changes. Do NOT fix any log items unless you are sure of what you are fixing. Get help here.
Start a new thread and post your entire HJT log. You will get help quicker if you start your own thread. Posting a HJT log in someone else's thread gets too confusing and there is a good chance it will get overlooked (or deleted).
Please be patient while waiting for help on your HijackThis log.
This should help with the preliminaries!
