New viruses are found all the time, so the virus definition file on your PC needs to be updated on a regular basis. Most computers are set up to do the update automatically for you, but there are times when you should update the virus definition file manually.
For instance, if there is a known virus outbreak on campus, you should update your virus definition file immediately.
