Using Rapid Release virus definitions is a proactive effort to prevent the spreading of a new virus.
Rapid Release virus definitions have undergone basic quality assurance testing by Symantec Security Response.
Applications such as Symantec End Point Protection 12 and Symantec Anti Virus Corporate Edition can be used to open these files.
This file extension is also associated with the Power Designer database and used as files that contain data such as definition and custom files.
To update the virus definitions on a computer without Internet or network connections Note: Effective Thursday, August 18, 2005, US Pacific Time, Symantec will no longer release virus definitions that are sized to fit a set of standard 1.44 MB floppy disks.
About a month ago, the Virus Definition File version date stopped updating and hasn't updated since - 3/26/2012 rev. The automatic update has continued to run everyday, downloading the latest definitions, but not updating the version date in the client. Sometimes it downloads an update successfully and other times it says the virus definitions are up to date.
Files with the extension are used as Symantec Virus Database Files and Power Designer Database Definition Files.
As Symantec Virus Database Files, files are actually virus database files mostly used by the anti-virus software created by Symantec.
In most cases, the easiest way to update virus definitions on computers that do not have Internet or network access is to download the single, large file and transferring it using a writeable CD or other portable media.
If you copy virus definitions files to a computer that you suspect is infected with a virus, be sure to use only read-only media, such as CD-R.
