yeah that's it. I've seen search results at the top with u_n_d_e_r_s_c_r_e_s before and from my experience they have always been apple ipod ads so I never download them.

I just assumed it was Limewires way of making money but now after reading your post I see theres much more to it.

But I don't know how anyone could force a download like that, even if it was an executable file it would still require a double click of your mouse right?

My knowledge on computers and internet is quite limited but I would guess the culprit is viewing incoming searches then renaming his virus.exe to what he sees and in return his virus is added to your search results?
