HTML document blocked on top of Desktop Image

Hi all
i have a problem that has been bugging me for the past couple of days, i have an html file that is covering my desktop image. it was loaded up from some website that i visted. ironicaly it is publicity for an adware remover, which asks 40$ us to buy the program which i don't indend on buying. i noticed that if i closes the explorer process it goes away and i can see my desktop image, how do i remove this annoying html file?
all advice is accepted since i can't seem to anything about it i've tried a process manager but i can't seem to locate which file to remove.

thanks
