Installing New Virus Definitions Files ====================================== The following document details the virus definitions update procedures for: * Intelligent Updater * Norton AntiVirus Program Upgrades * Norton AntiVirus for Windows 95 versions 1.0 and 2.0 * Norton AntiVirus for DOS and Windows version 3.0 * Norton AntiVirus Network Manager version 3.0 * Norton AntiVirus for Windows NT version 2.0 * Norton AntiVirus for NetWare version 2.0 * Installing Virus Definitions Files Manually * Additional Information ===================================================================== Intelligent Updater ===================================================================== As part of SARC's continuing commitment to fight the spread of computer viruses, Symantec has developed a new program called Intelligent Updater to simplify virus definitions files updates. Intelligent Updater locates Norton AntiVirus on your computer and installs new virus definitions files automatically. All you have to do is run the program then scan your disk with Norton AntiVirus. Later sections of this document give step-by-step instructions for each Norton AntiVirus version. The Intelligent Updater program file is available in many on-line areas as well as distributed on the monthly virus definitions update disk. The program name, which changes from month to month, uses the following form: mmNAVyy.EXE, where mm is the month and yy is the year. For example, 11NAV96A.EXE is the virus definitions files update for November 5, 1996. ===================================================================== Norton AntiVirus Program Upgrades ===================================================================== If your version of Norton AntiVirus (NAV.EXE, NAVW.EXE or NAVW32.EXE) is dated before June 1, 1996, you should update it with the latest program updates available. As viruses continue to be discovered with alarming regularity, the NAV virus definitions files have grown in size to counter the latest threats. Applying the patches will ensure that your installation will continue to accept the latest (and largest) virus definitions files. Using older versions of Norton AntiVirus can cause false detections when the new virus definitions are installed. Norton AntiVirus 3.10 Engine Update (UPDATEME.EXE) -------------------------------------------------- To upgrade your Norton AntiVirus 3.0 program: * Download the file called UPDATEME.EXE * Place the file in an empty directory and execute the file to extract its components. * Enter: PATH; at the DOS prompt. Don’t forget the semicolon. This command temporarily disables your path statement and will prevent corruption of NAV Network Manager installations. * Run UPDATE.EXE to create a set of install files. To place these files on floppies and create a new installation disk set, enter A:\ when it prompts for a location to EXTRACT the files to. * From DOS, run INSTALL.EXE. * After applying this patch, you must also update your virus definition set. NAV for Windows 95 v1.0, 95.0b Large Volume Update (NAV95OB.EXE) ---------------------------------------------------------------- This latest patch also adds support for Microsoft Service Pack 2 (FAT 32/large volumes) and will be required to apply the December 1996 virus definitions set.
