The best 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

• In the client, on the Status page, next to Antivirus and Antispyware Protection, click Options > View Threat 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.
