The Adblock Browser for Android default settings allow you to see some nonintrusive advertising. To disable this, go to the three dots on the top right of the browser. Select Settings -> Ad blocking -> Acceptable Ads.
EasyList should already be enabled in your settings. To check on this go to Settings -> Ad blocking -> Ad blocking.
After this, you shouldn't be seeing ads. If you do, then you could be infected with adware.
If you need more help, just let me know.
