什么是间谍软件

间谍软件是恶意软件的不同类别，专门用于收集有关设备用户及其行为的信息，以及在未经用户了解或许可的情况下获得对设备的控制权。

尽管“间谍软件”一词​​本身表明这些程序跟踪用户活动，但今天该名称通常被更广泛地使用，并且还指严格意义上不是间谍软件的其他产品。这些产品执行各种功能，例如显示不需要的广告，将用户重定向到各种网页等。

Unlike viruses and worms, spyware cannot be distributed independently, so certain user actions are required to install it. In this sense, spyware is somehow similar to Trojan horses. Spyware can be installed on an unsuspecting user's computer by means of conventional social engineering techniques. Many "free" programs offered on the Internet actually contain this type of malware inside. In some cases, applications that promise to clean the device of spyware, are actually spyware or additionally install spyware.
