I use Real Player to listen to listen to the radio, just recently when I open Real Player it runs an advertisement on the drop down on the top of the page. No advertisement is displayed and no sound is heard, it lasts for about 5 seconds. When I clicked on the info for this it says in the title “advertisement” and the file name “ad.uk. double click.xxx” (the file name extension is .net) I thought by altering the default location (to Germany) would get rid of it, but when I log on again it reverts back to the UK default. Has anyone got any idea what this is, and how I can get rid of it? My OS is XP Home.
