Rootkit和广告软件之间的区别

1. Rootkit：
Rootkit是一套应用程序，是一种旨在感染目标PC并允许攻击者安装一组工具的恶意软件，这些工具可以授予他对计算机的持久远程访问权限。该恶意软件通常将自己伪装成“隐藏在普通视线中”的普通文件，因此您的防病毒软件会忽略它们。它使管理员级访问计算机或计算机网络成为可能。目的是从您的计算机上窃取身份信息，通常是为了获得对系统的控制权。很难检测和删除，需要专门的工具才能删除。

2.广告软件：
广告软件并非完全恶意，但出于恶意目的，它们确实破坏了用户的隐私。它们在计算机的桌面或单个程序内显示广告(出现弹出窗口)。它们主要附带免费使用的软件，因此是此类开发人员的主要收入来源。他们基本上会监视您的兴趣并显示相关的广告。攻击者可能在软件中嵌入了恶意代码，广告软件可以监视您的系统活动，甚至可能危害您的计算机。
