Hello, Michael,
Some browsers have Adblockplus as "add-ons".
If you have Firefox, Opera, Dolphin, you can enable them in Settings.
Probably on more browsers, too.
On this tablet of mine, I have Adblockplus installed.
Download it from Google.
You may have to configure the wifi settings, but that is easy enough.
Adblockplus, ublock, etc are free.
