Now look at the ads-what are they for? Virus laden websites/fake installers. This is for a major keyword-why is Google allowing their ad pool to be poisoned by such bad/misleading ads?
In the past people's computers would get trashed from popups and malicious web pages, but today most of the junk filled computers I see have the same story 'I was looking for xxx on Google and I clicked the first link and then a bunch of stuff started popping up...'
When Google, the biggest 'best' ad provider in the industry, is polluting computers like this, why shouldn't people run Adblock?
