Did you ever wonder how antivirus software knows how to counter the latest threats? How does it know about the latest viruses on the Internet? Aside from the fact that antivirus software analyses the behavior of programs, it also relies on some signatures of viruses. These are called virus definitions and are constantly updated to keep the protection software up to date with the latest threats. This is why it is important to download and install the latest McAfee Virus Definitions periodically. The program is able to run the update automatically and download the files from the online servers.
However, if you are offline for long periods of time or are on a metered connection, you need to download the signature files manually and have the antivirus incorporate them into its database.
These files have a DAT extension and also come with an XDAT installer that makes it easy for you to install the signatures into the antivirus. Having the latest signatures at all times means that your McAfee product is able to prevent almost all types of attacks made against your computer.
Remember that the Internet is a dangerous place and hackers are always on the lookout for new victims.
