In Windows XP service pack 2 , Microsoft has added
some
features to the Internet Explorer 6 browser. These include a pop-up stopper and
an add-on manager for configuring ActiveX components and are discussed here.
Pop-up Blocker
One of the most annoying modes of Internet advertising is the unsolicited
pop-up window and its variations such as pop-unders, etc. In spite
of the fact that pop-ups are very irritating, marketing agencies claim
that they are effective and persist in using them. To defend against these
intrusions, many varieties of pop-up stopper have been available for some
time. Microsoft finally joined many other browser offerings and put a
pop-up stopper in the Window XP SP2 version of Internet Explorer 6 (IE 6).
There is now an added entry "Pop-up Blocker in the Internet Explorer "Tools"
menu as is shown below.
The pop-up blocker can be turned off or configured for individual Web sites
in the Settings dialog shown below. There is also a "Filter Level" to
adjust how stringently pop-ups are controlled. Some pop-ups are useful,
providing additional information on some subject or expanding a menu.
Usually, however, these require the viewer to click or pass over a link
and do not appear automatically. If you would like to test the level
of your defenses against pop-ups, try this test

Add-on Manager
Another new entry in the Internet Explorer "Tools" menu is the
Add-on Manager as indicated in the figure below. An "add-on" is something
that helps IE carry out a function that it can't do itself or creates
new functionality. Common Examples are the Adobe Acrobat reader for PDF
documents, the Google toolbar, and the Macromedia Flash player. They
are normally what is called "ActiveX" objects. (See this
page for a description of ActveX.) There are many useful objects but
there is also malware designed to use this particular way to infest your
computer.
The dialog for managing add-ons is shown below. Useful ActiveX add-ons
can be updated in the manager. Any object that is suspicious or causing
system instabilities can be disabled here. Note that this only disables
the use of an object by IE. Other components of your system can still
use a disabled ActiveX object.
More about the changes in SP2 can be read at this Microsoft
article. The specific security changes in Internet Explorer 6 are discussed
here.
