Hi Ianmac
Please go
Here and unzip the newest version of HJT into a new dedicated folder,
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.
Most things are harmless and needed so don't make any changes.
post a log here please.
This will show us whats running and what OS you have, As well as any spy/adware you may have on your computer, Which may or may not be causing your problems, Its a good place to start.
Stumble It!
