There are ad-blocking add-ons for just about every modern browser out there, I tend to use Google Chrome, but there are add-ons available for IE, Safari, Firefox, Opera, etc.
Below is an example of what the stream looks like without adblocking software installed, followed by the same stream while Adblock is running.
This is a screen-captured video of the wiz1.net video link without any adblocking software installed. Notice: 1) how many freaking ad's there are and 2) how clicking the 2 buttons used to close out the ads actually open a pop-up. That's because there are invisible ad-layers on top of the frame.
It takes all of 30 seconds to get up and running and will make viewing these streams much safer. Just google "(your browser) adblock" to get started.
