These Google AdSense ads are a bloody nuisance !
They are so laced with malware these days as to pose quite a a threat in themselves, to the unwary. When training newbie folks in how to use the internet (it still happens), I have to point out the dangers of clicking on Google AdSense ads and advise my clients to just ignore them, as it's safer.
Which makes me wonder about the Value For Money that the paying advertisers are getting. And being linked to malware infections isn't going to be good for any company's rep.
