"Eliminates most pop-ups"
Very easy to install, works as advertised on most pop-ups, and requires no afterthought -- definitely a fire-and-forget type of program.
It doesn't get all pop-ups.
This website http://www.kephyr.com/popupkillertest/index.html?source=stpltest tests the functionality of pop-up killers, and Stop-the-Pop-Up Lite 2.56 kills 80%-90% of the various pop-up types. But it appears there is no pop-up killer that gets 100% of them, so I am happy with this program that gets most of them easily for free.
A couple of notes regarding previous comments. First, the instructions are petty straightforward. The first time it killed a window I was trying to open, I looked through the manual, read again how to bypass the program with ctl+shift, and never had a problem again. Second, I don't think it installs any spyware or adware. Just because ad-aware identifies something as adware does not necessarily mean it is adware -- it means the program shares some of the same characteristics as adware, characteristics the ad-aware program is looking for. That's why adware and spyware programs usually have a disclaimer telling you to be sure you don't need something before deleting it after you run a search. I don't know with certainty there is no adware, but until I see definitive proof that Stop-the-Pop-Up Lite 2.56 actually installs adware, I'm not going to worry about it.
