I have uninstalled Mackeeper, however still getting pop up ads all over the place when I use Safari. What can I do to get rid of these? Unfortunately I'm not a very technical person so would like something in plain old English please. Thank you :)

Hi Guys,

I'm fairly new to Apple- have a Macbook Pro with Retina. Operating on version 10.10.3. I made a huge mistake of installing MacKeeper on my laptop a few days ago- have managed to uninstall it (I think), delete it from Trash and restarted. However, whenever I use Safari there are pop ups and anything I click on opens up one of these new screens. Getting a bit frustrated with it- in simple terms how can I get rid of this? I am not a very technical person so anything in plain old english would help. Thanks in advance 🙂
