A pop up blocker is a pop up blocker and if it works for you, great. Personally, I don't like the extra "weight" that's added with one more toolbar.

My preference for surfing safely in Internet Explorer,(at least as safe as can be expected in IE) without pop ups, is to "diable" or "Prompt" the internet security settings and to use a HOSTS file.

What is the Hosts file?

And to be even safer while surfing the net, use an alternative browser that isn't vulnerable to the pop ups in the first place. Something like Mozilla, Firefox, etc. make for great internet surfing and don't require any extra toolbars or pop up programs.

Hope this helps.
