It is always confusion in the terminology of the virus to clean some viruses, known as the Trojan Horse and worm that are viruses but this is false because each of these types of programs has its own method .

- Trojan Horse: Trojan horses completely different about the virus and worm as it was designed to be a nuisance rather than a harmless virus, such as when the user visits a Web site on the internet it will order from you sometimes agree to download a specific program to show the page, or to run a file on the site to make user believes that he is dropping the program is in fact Trojan which shall sometimes erase some of the icons on the desktop or delete some system files and some of your important data also causes a change in the Home web browser and are not able to browse and some of the advanced types of programs Trojan put holes in your computer called the Back door and through the program for the transfer of your data to the other party without your knowledge and this is serious matter.
