I would advise you look at properties for that avg exe file C:\Program Files\AVG\AVG8 because it isn't the same as the file path i have known avg to use, and the name is not the same. just see if that exe file is digitally signed by avg. If by doing that you can see this is just a matter of avg having problems (not something pretending to be avg) then http://www.avg.com/gb-en/utilities has some removal tools on it, i used one when i reinstalled avg a while back. Are you able to perform downloads at all to get hold of the tools i or anyone else has mentioned? how many browser do you have, how many of them have you tried downloading with? what exactly is the prompt/warning that is brought up when a download is stopped, does it happen only for downloads of certain file types or for absolutely everything (right click an image, "save image as... " and see if downloading a simple jpg or png is prevented)? If not i can see a way you could get the exe files you need onto your system.
