I recently got comcast internet and i installed Mcafee and like two days later my computer started to have a massive amount of pop ups and in the matter of hrs my computer was not able to acess the internet! Every thing was moving slow. I uninstalled the comcast offered McAfee and this seem to help but the problems still exist to a lesser degree! My computer is old but it worked fast and fine before all this is there a way to fix this please if you know of a way!
