病毒、蠕虫和特洛伊木马的区别

病毒：
病毒是一种计算机程序或软件，它将自身连接到另一个软件或计算机程序以危害计算机系统。当计算机程序运行时带有病毒，它会执行一些操作，例如从计算机系统中删除文件。远程控制不了病毒。

蠕虫：
蠕虫也是一种类似病毒的计算机程序，但它不会修改程序。它越来越多地自我复制，导致计算机系统变慢。蠕虫可以通过远程控制。

特洛伊木马：
特洛伊木马不会像病毒和蠕虫那样自我复制。它是一段隐藏的代码，可以窃取用户的重要信息。例如，木马软件在进入网页浏览器进行登录时观察电子邮件ID和密码。

病毒、蠕虫和特洛伊木马的区别：

Virus	Worm	Trojan Horse
Virus is a software or computer program that connect itself to another software or computer program to harm computer system.	Worms replicate itself to cause slow down the computer system.	Trojan Horse rather than replicate capture some important information about a computer system or a computer network.
Virus replicates itself.	Worms are also replicates itself.	But Trojan horse does not replicate itself.
Virus can’t be controlled by remote.	Worms can be controlled by remote.	Like worms, Trojan horse can also be controlled by remote.
Spreading rate of viruses are moderate.	While spreading rate of worms are faster than virus and Trojan horse.	And spreading rate of Trojan horse is slow in comparison of both virus and worms.
The main objective of virus to modify the information.	The main objective of worms to eat the system resources.	The main objective of Trojan horse to steal the information.
Viruses are executed via executable files.	Worms are executed via weaknesses in system.	Trojan horse executes through a program and interprets as utility software.
