Hi nuttytuter,
It would appear that someone has placed a corrupt wpad file in the path of the site you are accessing. Avast is stopping the file being executed, but there seems to be a copy lurking on your system that is accessed every time you start to browse, thus triggering your avast av again.
Essexboy will certainly get rid of all the remnants of it. All temp internet files should be searched on your computer for any wpad.* files and then deleted,
