A Trojan horse virus occurs in infected documents, programs and executable files. They appear as something you would be familiar with so as to trick you into opening the file.
A Trojan or virus often adds programming to an exe file which changes the way Windows works when it tries to use the file. Instead of using the proper file, Windows is directed to the Trojan or virus and does what that files orders it to do. After a virus or Trojan is removed by an antivirus application, the damaged exe files will probably have to be replaced. For Excel and Word, for example, reinstall Microsoft Office. The files created by Excel or Word should then work properly again. It is always best to update your antivirus applications. Don't visit sites you don't trust.
