Define what a file-infector virus is.

What will be an ideal response?


?File-infector virusesattach themselves to executable files. When an infected executable file runs, the virus copies itself to memory. Later, the virus attaches itself to other executable files. Some file-infector viruses attach themselves to other programs even while their"host"executable runs a process in the background, such as a printer service or screen saver program. Because they stay in memory while you continue to work on your computer, these viruses can have devastating consequences, infecting numerous programs and requiring that you disinfect your computer, as well as reinstall virtually all software.
