The Purpose Of Virus Definition Files
Throughout the course of a year, new computer viruses come out from time to time. It becomes very important for your anti-virus software to be able to update itself with the service provider for virus definition files. These files "explain" the function of new computer viruses and also carry instructions as to how to protect against them and remove them from your computer. As the end-end user, it is up to you to set the frequency of these periodic updates for virus definition files. Once the anti-virus program adds these files to its database, your computer is immediately secured from being infected by the new viruses.
