Congratulations on making a very wise decision regarding your personal computer internet security with respect to buying antivirus software. If by some chance you are reading this article and are still unsure of the need for an internet security system for your computer and /or network, I invite you to read my earlier article Computer Internet Security: How Viruses Can Destroy Your E-Business.

Now that you are ready to take the plunge and spend some money on internet security products such as antivirus software, it is important to understand exactly what this protective software does. Basically antivirus software has three goals:

To prevent a virus infection from reaching your computer/network system before any damage can be done. The antivirus software has a database containing the virus identification (called signatures) of all known viruses (at the time the software was created), and this can run into thousands of signatures. When you download information to your computer or network from an outside source, be it the Internet or a disk, the antivirus program scans the incoming information for any of the virus signatures that are in its database. If a virus is identified, you are notified, before the downloaded information is allowed entry into your computer or network. Provide a first line of defence against incoming virus threats, if the software is installed on a computer network, so that the network administrator has time to take action to stop the virus from entering the system, or if already there, keep it from spreading and then disinfect (clean) any parts of the network that have been corrupted by the virus. To take the necessary steps to clean and repair your computer and/or network by either eliminating the infection and repairing damaged files or moving the corrupted files to a safe or quarantine area so that no further damage can be done by the virus.

Understanding what an internet security system should do is only one part of the journey. It is also very important to be able to make an informed decision as to the best internet security software that will meet your requirements from the many internet security products currently available.
