卸载微软流氓插件.NET Framework Assistant
Microsoft .NET Framework 3.5 Service Pack 1的更新中，Windows的升级服务程序会偷偷的给用户装上一个名为Microsoft .NET Framework Assistant的Firefox扩展，而且不允许用户卸载。
这个插件允许网站在用户不知情的情况下在用户电脑上安装软件。这是一个非常严重的安全漏洞，它使得FireFox变得和微软自己的浏览器Internet Explorer一样，对恶意软件门户大开。
下面给出卸载的步骤：
- 打开注册表编辑器 ：在开始菜单搜索框（在Vista或Windows 7） 或者 运行窗口（XP）输入 regedit .
- 展开注册表项
- 32位的系统 : HKEY_LOCAL_MACHINE \ SOFTWARE \ Mozilla \ Firefox \ Extensions
- 64位的系统 : HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Mozilla \ Firefox \ Extensions
- 删除右边面板中值为{20a82645-c095-46ed-80e3-08825760534b}的项
- 关掉注册表编辑器
- 打开Firefox浏览器，在地址栏输入about:config ，然后回车
- 搜索关键字 microsoftdotnet，就可以找到 general.useragent.extra.microsoftdotnet设置.
- 在 general.useragent.extra.microsoftdotnet上点右键 , 然后选择Reset（重置）
- 重启Firefox
- 打开文件夹%SYSTEMDRIVE%\Windows\Microsoft.NET\Framework\v3.5\Windows Presentation Foundation，其中%SYSTEMDRIVE% 表示你的系统盘，一般是C:\
- 删除文件夹DotNetAssistantExtension
- 在Firefox中打开Add-ons 窗口，确认 Microsoft .NET Framework Assistant扩展被成功删除
