There is a very new threat that has emerged- is protection provided by the definitions currently is use by the Symantec Endpoint Protection (SEP) client on my computer? Or, do the definitions currently in use by Symantec Endpoint Protection (SEP) still provide protection against very old threat families? How can this be confirmed?
Please see An Antivirus vendor detects XYZ virus. You want to know if Symantec detects it for details on how to search for detection infromation based on a specific name or MD5/SHA256 hash value.
Another way to check if a threat family is covered by the definitions that a SEP client is currently using is to check the current Detectable Risk List. Compare that list to the name of the specific threat that is a concern.
To view the risk list
Please note that different AntiVirus vendors often use different names for the threats that are discovered. The name that Symantec Security Response has assigned to a threat may not match the name which appears in news reports.
Also note that there are many new variants of known threats discovered daily. Always ensure that definitions are kept up-to-date on all SEP clients, and please submit any suspicious files to Symantec Security Response for analysis so that protectcion can be updated.
