It pisses me off too when my machine gets messed about with - lot.
The worst I came across was lop.com - not when you visited the site, but through pop-ups at other sites. It did the usual trick of altering your home page to their site but you couldn't change it back because, whenever you changed the home page to what you wanted, their little prog in the computer changed it back to lop.com. It took some time to research it and find and delete the files.
So, eyelfixit, -
FIX IT!!!
I won't be offering him any help of any kind until he's fixed it and announced it here.

I forgot to mention - I figured that lop.com owed me for the time it needed to rid my machine of their stuff, so I stole and used their graphics
