I have had this issue for 2 days and it Is Avast warning me that the site I am on is attempting to download a virus, it is an ad from one of the many ad sites that WGT is allowing to run unfiltered on the game. Everything that happens with WGT is not always the players fault, if we have learned anything over the years, It is a constant battle with the browsers. This is happening to me on IE since it is the only browser that works for me since the November update, Firefox, Maxthon and Pale Moon have all gone beserk, funny they all worked the night before that update.
