Unfortunantely their is no way that I know of to download
the latest Internet Explorer with the built in popup blocker.
This refers to it being builtin to Service Pack 2 as we all know.
This link works for downloading the full version of Internet
Explorer but I haven't found a way for the latest IE version.
You can download a toolbar plugin with a popup blocker
builtin. The babelfish toolbar allows you to translate
foreign websites and also includes a good popup blocker.
I have heard the Google Toolbar which has a builtin
popup blocker is good also.
