Warning: You might be at risk! Microsoft’s .NET Framework 3.5 Service Pack 1 plugin for Firefox is the cause

Last February, Microsoft released an update for the .NET Framework 3.5 Service Pack 1 via Windows Update. It turns out that along with the update, a plugin was automatically installed in the Firefox browser. Moreover the plugin was practically impossible to uninstall or delete through Firefox Add-ons manager. A method to escape the threat was a real headache and a dangerous operation, as it implied to manually look in the registry and delete the harmful keys.
