A recent news article has shown some serious and still-existent flaws with the security in Microsoft Internet Explorer. Please read the following on how to protect your computer:

On top of this, I have also installed Mozilla (http://www.mozilla.org) web interface and completely nixed Internet Explorer from my system.
Just a little personal recommendation that others do the same.
and yes, you can still log in and tune in to GSP with Mozilla...although it will ask you to "select the program" with which to open the .pls file that is the stream. Simply browse to /program files/winamp/winamp.exe on your computer and select "use this from now on" or whatever.
