Hi...
Download HijackThis
*danborg.org/spy/HJT/hijackthis.exe
Put HJT in a permanent folder. Here's how to make the folder:
Click My Computer, then C:\
In the menu bar, File->New->Folder.
That will create a folder named New Folder, which you can rename to "HJT" . Now you have C:\HJT\ folder. Put your HijackThis.exe there, and double click to run it.
