NET and Firefox
February 27, 2009 - Warning to all Firefox users: the Microsoft .NET Framework 3.5 Service Pack 1 update, pushed through the Windows Update service to all recent editions of Windows, installs the Microsoft .NET Framework Assistant firefox extension without asking your permission. This update adds to Firefox one of the most dangerous vulnerabilities present in all versions of Internet Explorer: the ability for websites to easily and quietly install software on your PC. Since this design flaw is one of the reasons you may've originally choosen to abandon IE in favor of a safer browser like Firefox, you may wish to remove this extension immediately. Unfortunately, Microsoft, in their infinite wisdom, has taken steps to make the removal of this extension particularly difficult - open the Add-ons window in Firefox, and you'll notice the Uninstall button next to their extension is grayed out! Here's the complete removal procedure.
