Can someone recommend...

An ads system that pays to paypal?

That isn't a popunder, doesn't contain spyware, and has a decent pay-per-click.

Yeah I recommend you try Clicksor.com.

I am currently with clicksor and am quite pleased with their system and payment method. They offer a low payout rate with payment through paypal.
