Pop up ad blocker?

What are you guys using to fend off the annoying barrage of ads?
Anything free, and doesn’t require personal info?

AdGuard on my iPad. 
I use Kasperski Total Security which includes an ad blocker which works very well.  The only downside is that it somehow blocks the Audiogon "New Today Listing" banner on the front page.  Anyone else experiencing this?
adblock plus, never adblock.

adblock is the fake, adblock plus is the real original.

Adblock sells your data, adblock plus is a one man operation who was there first, and had kept his integrity.
