什麼是間諜軟體

間諜軟體是惡意軟體的不同類別，專門用於收集有關設備用戶及其行為的信息，以及在未經用戶了解或許可的情況下獲得對設備的控制權。

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.
