我正在做个关于特洛伊木马的课件,需要全英文解释的木马病毒的英文解释,

A Trojan horse, also known as a trojan, is malware that appears to perform a desirable function but in fact performs undisclosed malicious functions. Therefore, a computer worm or virus may be a Trojan horse. The term is derived from the classical story of the Trojan Horse.
Types of Trojan horse payloads
Trojan horse payloads are almost always designed to cause harm, but can also be harmless. They are classified based on how they breach and damage systems. The six main types of Trojan horse payloads are:
* Remote Access
* Data Destruction
* Downloader
* Server Trojan(Proxy, FTP , IRC, Email, HTTP/HTTPS, etc.)
* Security software disabler
* Denial-of-service attack (DoS)
Some examples of damage are:
* Erasing or overwriting data on a computer
* Re-installing itself after being disabled
* Encrypting files in a cryptoviral extortion attack
* Corrupting files in a subtle way
* Upload and download of files
* Copying fake links, which lead to false websites, chats, or other account based websites, showing any local account name on the computer falsely engaging in untrue context
* Falsifying records of downloading software, movies, or games from websites never visited by the victim.
* Allowing remote access to the victim's computer. This is called a RAT (remote access trojan)
* Spreading other malware, such as viruses (this type of trojan horse is called a 'dropper' or 'vector')
* Setting up networks of zombie computers in order to launch DDoS attacks or send spam.
* Spying on the user of a computer and covertly reporting data like browsing habits to other people (see the article on spyware)
* Making screenshots
* Logging keystrokes to steal information such as passwords and credit card numbers
* Phishing for bank or other account details, which can be used for criminal activities
* Installing a backdoor on a computer system
* Opening and closing CD-ROM tray
* Playing sounds, videos or displaying images
* Calling using the modem to expensive numbers, thus causing massive phone bills
* Harvesting e-mail addresses and using them for spam
* Restarting the computer whenever the infected program is started
* Deactivating or interfering with anti-virus and firewall programs
* Deactivating or interfering with other competing forms of malware
* Randomly shutting off the computer
* Installing a virus
* Slowing down your computer
* Displaying pornographic sites
Methods of deletion
Since Trojan horses have a variety of forms, there is no single method to delete them. The simplest responses involve clearing the temporary internet files file and deleting it manually. Normally, antivirus software is able to detect and remove the trojan automatically. If the antivirus cannot find it, booting the computer from alternate media(cd) may allow an antivirus program to find a trojan and delete it. Updated anti-spyware programs are also efficient against this threat.
