There are a lot of fake channels solely for the purpose of luring viewers with ads, but here is how you can avoid any potential hiccups with pop-ups and ads.

--Do not download anything that is suggested.

--For every ad, there is an "X" button. It is typically in a corner or out of the way so it is hard to see. Sometimes ads try to fool you by giving you a fake "X" graphic which leads you to an ad. Do not be discouraged when this happens, the real "X" button is there somewhere.

--Multiple ads will pop and it takes a little bit to clear out each and every ad. Even then, pop-ups will occur as you clear the ads. Do not listen to any of these ads or pop-ups and clear them right away.

--"The Biggest Loser" season 15 finale live stream will have recurring ads that pop up every once in a while. If this is the only way you can view "The Biggest Loser," do not be deterred and the live streaming will work once the ads disappear.

Tune in at 9:00pm EST for "The Biggest Loser" season 15 finale.
