Virus Definition

Virus Definition is the database of viruses and other malware
that an antivirus software uses to scan a computer. Since, new
viruses are developed and released from time to time, it is
essential to update the virus definition at regular intervals. You
should set your antivirus software to automatically download
and update the virus definition when you connect to the
Internet.
