Some of them are good, but you mixed Ponzi Schemes in the middle and some sites I'm not sure if really pays, like the PTC sites offering a good reward, but with a high minimum withdraw amount.
Also, you promote downloadable software to earn money by surfing, I'm almost sure it's not a good idea.
All PTC Sites, as well as those with a high minimum withdraw amount (like 4BC Network), really pay.
I get payouts from all sites.
Downloadable software from MyCashBar is safe. There is shown only one banner rotator at the bottom of your browser.
