What is wrong with my laptop? - 1

A few months ago i got a Lenovo Y510p and for the first month it ran pretty well. But after the first month it started run slower, more ads, and have pop ups. Whenever i start my laptop pop ups such as PC fix speed, reg clean pro, My PC Backup, Optimizer Pro and many more. I just want my laptop to work like before can someone please help?

If your running windows 7 go to start then click computer a window will open. At the top of that window you will see an option uninstall or change a program. Click on that and you will see all the programs you have installed.jus uninstall all those programs that are popping up. Hope this helps
