Chrome browser problems

l use to love using my Chrome browser on my MBR but now browsing is not as pleasurably easy, eg when browse, eg doing a speedtest.net frequently the page will go to another page, often l get windows which just pop up eg "MacKeeper","FlixJunky". l can't even access my HSBC internet banking since it no longer allows pop up which is essential. I have deleted all history, cookies, but this still happens, do l have to uninstall Chrome and reinstall? My safari also doesnt allow pop ups and has the annoying pop up screen "MacKeeper". please help me get them back to how they use to be.
will MacKeeper help?

Lol avoid Mackeeper like the Black Death. If you don't want popus try Adblocker and Ghostery may also be of some help.
