This is only occuring with tek-tips.com web site. Any time I look at an issue the web browser goes to googleads.g.doubleclick.net anywhere from 6 to 10 times. This means that I can't hit the back button to go back to the list of issues. This means that I might have something installed on my pc, assuming that I am the only one having this issue. Has anybody else seen this and does anyone know how to get remove this?
