Free Antiviral Software

This brief article will explain why antiviral software is essential to the health of your computer system and which free antivirus packages are the best to install and use.

Antivirus software is an essential item in securing your computer system from viruses written intentionally to harm your computer system and your personal data. Antivirus software does this by scanning your computer system and finding any virus on your computer. In order to identify a virus, the antiviral software will have a database of virus definitions attached to itself, every part of your computer system will be scanned and each file will be checked to see if it matches any known viruses. If a known virus is found it will be placed into a vault, or secure area controlled by the antiviral software, and deleted. Most free antivirus software packages will only delete a suspected virus after checking with you to make sure that it isn't a personal file of yours.

The virus definitions database is often automatically updated daily by the software package, or can be configured by you to do update daily, in order to maintain its effectiveness against known potential viral threats. As you have probably already gathered, antiviral software is only as good as the virus definitions database that it uses, and this is why some really good software doesn't get chosen as often as others do, as they don't have a great definitions database.

The wider the user base and the more people using the software package, will often improve the definitions database as their individual feedback and experiences will contribute towards an improved database of viral definitions.
