Every VIPRE product features automatic virus definitions update, allowing the application to get the latest signatures without user intervention. Provided the computer is connected to the Internet, this task is running in the background without interfering with the user's work.

However, it sometimes may happen that the Internet connection is not available. This kind of situation doesn't have to be an impediment when trying to keep the virus definitions up-to-date and thus, make sure the computer is protected against the latest viruses. As an alternative to the automatic updates, users of VIPRE products can manually install the most recent virus definitions.

The procedure is fairly simple: the user must get to a computer with Internet connection and download the latest virus signature file from the official page provided by VIPRE. As a reminder, one must make sure the file it downloads is compatible with the VIPRE product on their computer (be it Vipre Antivirus, Antivirus Business, Internet Security, etc.) and its version (there might be different releases for 9.3 and 9.0, for instance).

Once in the possession of the signature file, the next step is to copy it to the offline computer. The manual update of the threat definitions requires the user to navigate to the 'About' window in the 'Account' tab and then choose 'Support Tools'.
