It copies a small bit of code into your computer that enables the writer of said code to have remote access to your machine. It is similar to a program like PCAnywhere, or any other remote admin software...except evil.
More Information:
A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.
The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware. Malware includes Computer Viruses, worms, Trojan horses, most rootkits, spyware, dishonest adware, crimeware and other malicious and unwanted software), including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer system's hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious.
Most personal computers are now connected to the Internet and to local area networks, facilitating the spread of malicious code. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, Instant Messaging and file sharing systems to spread.
It can steal passwords or damage files.

A Trojan Horse (a particular type of Trojan) has the ability to perform malicious functions on the host computer. It can allow a hacker remote access to your computer and take complete control of your computer without you even knowing. The infection will at best make your computer extraordinarily slow and inundate you with many popups, especially about dating websites. At worst, it will leave your personal and sensitive information such as banking and credit card information at risk of being stolen.
Most trojan viruses are not going to directly hurt your computer. there goal is not to cause harm to your computer. Instead, they want to leverage your computer to do 1 or 2 things.
Some trojans will cause slowdown as they suck away CPU cycles.
It depends on which Trojan you have. Some just display a message and other are far more nefarious. If your anti-virus software indicates which one you have then simply Google it and you should get results from COMODO,Symantec, McAfee, and other anti-virus vendors that include details of what the Trojan does and how to remove it.
I will tell you that many security experts think that once you have a Trojan infection the best course of action is to wipe the computer clean. That is because modern Trojans download and install other malicious software, which may download and install other software. The result is that even if you know the extent of the infection (which you probably don't) it is nearly impossible to remove all infections
