How can I reduce unwanted ads in browser on Samsung Galaxy Tab Pro 12.2?

[Abby Normal]

So I want to buy a ceiling fan. I went to a website and browsed through their Web site. Every since then every Web site I go to gets an ad from them that pops up with a little blue flag in the upper corner. How do I get rid of this or do I need to install some kind of anti malware or anti virus
