Keeping your computer protected from malware, spyware and other type of threats does not just meant to install an anti-virus application on it, but also to make sure that the security tool is always up-to-date and capable of blocking even the newest kind of attacks. One of the manners in which you can ensure that is always to have the latest virus definitions installed on your computer, and those of you who are using McAfee can do so by downloading and installing McAfee Virus Definitions. The tool comes in the form of a .DAT file that includes the latest virus signatures, paired with other information that anti-virus products use when it comes to keeping PCs safe. New .DAT files are regularly released, so as to offer protection against the hundreds of new malware that emerges each month. All McAfee products that use virus-scanning engine version 4.3.20 (or later) are compatible with these DAT files and users should keep them updated at all times. You can get more information about the updating procedure by accessing this page. The XDAT (DAT Package Installer) files available for download from McAfee also include an executable that automatically installs the DAT files. Users might also come across Compressed DAT Packages, which include an archived DAT file, and SuperDAT Package Installers (SDAT files), which might include a new scanning engine in addition to the DAT file and an installer. You can read more about what package is right for your product on this page. With the latest McAfee Virus Definitions installed on your computer, you can make sure that your McAfee product can block online attacks, find and delete malware from your computer, and keep your personal information safe at all times.
