[QUOTE 2524587, member: 9609"]Someone I was talking too recently got tricked into downloading something by the name of "Shopping Sidekick" whilst installing Firefox. It turned his computer into a non stop advert - he reckons he was getting adverts popping up in the middle of excel - he had to get an expert to sort it out, cost him £50[/quote]
I've been using Firefox for years and have never had any toolbars/programs installed with it. The installer never gave an option either so i would guess they downloaded a version from somewhere other than Mozilla site. It wouldnt be the first time installers have been changed in this way.
I bet it was added while installing another program. A lot of them add toolbars to browsers automatically unless you use the advanced set up feature.
