What is "Microsoft .NET Framework Assistant Firefox Extension" and what does ClickOnce Security Fix 1 do?


In the Microsoft .NET Framework 3.5 Service Pack 1 update, available to all Windows editions since February 2009, there is a program called Microsoft .NET Framework Assistant Firefox Extension. This application presents a dangerous vulnerability once installed in Firefox because it allows the websites you visit to automatically download software to your computer without even asking your permission!

What’s worse, the uninstall button is grayed out in Windows XP versions making this program impossible to remove without hacking the registry.

Now frustrated PC users can take back control of their computers in just minutes with ClickOnce Security Fix 1. Software Candy has come up with a simple solution to this serious security threat that doesn’t involve any risky changes to your registry.

As with all Software Candy products, ClickOnce Security Fix 1 is completely free of any viruses or spyware (digitally signed for authenticity and integrity) and is well tested for its advertised features. If ever needed, you can also uninstall it completely with a single click, performing a total cleanup after itself.

Take back control of your computer’s downloads in one simple step with Software Candy’s ClickOnce Security Fix 1.
