As an aside, I wonder how prevalent the adware would be when searching for "download chrome"?
µBlock is especially good for this as some of the lists have additional rules specifically targeting malware sources, and it can block things like actual script tags and such instead of just hosts.
Well it's not there to sell cars so much as it is to say to the public "BMW are valid cars"
So just having the advertisement get seen is what's important to them. At least that's my understanding. Evaluate the argument for yourself: http://www.reddit.com/r/explainlikeimfive/comments/14y695/el...
It's also another reason I filter ad's. I'm afraid they will manipulate the way I think.
