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。

Although the term 'spyware' itself suggests that these programs track user activity, today this name is often used more broadly and also refers to other products that, strictly speaking, are not spyware. These products perform various functions, such as displaying unwanted advertisements, redirecting users to various web pages, etc.

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.
