How Does this Affect Me?
Macros are simple programs that are used to repeat commands and keystrokes within another
program. A macro can be invoked (run) with a simple command that you assign, such as
[ctrl]+[shift]+[r]. Some viruses are macro viruses and are hidden within a document. When you
open an infected document, the macro virus runs. A macro virus can save itself to other files (such
as the Normal template) and can potentially infect all of your files. If a user on another computer
opens the infected file, the virus can spread to their computer as well.
