Can't get rid of ads in Safari. Please advise something.
I have macbook late 2011 model and using Yosemite OS. I have installed 2 to 3 ad blocker extensions but still no matter what website i click or what page i click, it opens up new links and some of them says about virus and some don't. But the thing is its getting really hard to use this because of ads. Cant use or open any website without opening a ad, and then most of the time i have to quit safari in order to get rid of that ad.
MacBook Pro (13-inch Late 2011), OS X Mavericks (10.9)
