is ther anything that can be done to stop the pop up from bangbus even when you download an innocent mpg file you get this annoying pop ups from BangBus

the words innocent and bangbus do not go together...like oil and water...
not that I have any idea what bangbus means (cough cough)

Those probably aren´t MPEGs, they rather are the gift of M$ - ASF.
Get a program that can play them without loading the webpage - like an old version of VirtualDub(they had to remove the ASF-Support) and convert to AVI.
