The last couple of days every time i visit the site after a couple of seconds the text scrolls down "this site wants to install "Adobe pflash player etc" Click on the cross to delete it and it reappears when i open the next thread. Not only do i find the text scrolling down very irratating but it adds 20 secs or so every time i change thread and it adds up.
So can any more IT literate member tell me (in very baby steps please

how i can permenantly delete it . ta.
