There are a few simple cures for this nonsense.
First -- use
Opera instead of IE or Netscape. It has the ability to selectively enable or disable pop-up windows, Javascript, embedded audio or video, and so on. Yes, IE and NS can do this too, but Opera puts those options in a convenient top-level "quick menu" (just hit F12 to bring it up) rather than making you drill down through layers of configuration options, making it easy to turn them on and off as needed.
Second -- edit your HOSTS file to point all of those ad servers back to your local machine. (Instructions on how to do this, along with pre-made HOSTS files you can use for this purpose, can be found in many places; just search Google.

) Whenever your computer needs to look up an IP address, it will always check the HOSTS file for a match before it goes to your internet provider's DNS server, so adding the advertising servers to your HOSTS file with an address of 127.0.0.1 -- which is reserved to mean "local machine" -- makes your computer try to load the banner ads and such from itself. (And since they don't exist on your machine, of course, all you get is the "broken link" icon instead of the banner ad.

)
Third -- use a program called eDexter. It's a faux proxy server that resides on your system and offers up its own tiny image file anytime something asks for one from 127.0.0.1. This, among other things, prevents problems with Javascript code that halts the loading / displaying of a page until all images are successfully loaded. (Without eDexter, such pages will, if you use the HOSTS trick above, wait indefinitely for the images they want to be loaded -- which, of course, they can't be since they don't exist on your machine.)
I have all three measures in place, and I'm not seeing
any of the stuff you guys are talking about.
