Took my computer to computer shop. They brought up Pprune on one of their computers and sure enough lots of advertisements. I was told nothing wrong with my computer and the advertisements are the result of Pprune selling advertising space often unrelated to aviation. So until Pprune owners change their advertising policy we Ppruners are stuck with being a captive audience to variety of advertisements like commercial TV. Never though I would see that happen. It didn't under the former Pprune days under Danny.
