Hi again,
That file (MD5 87C08D0EBFFFDB9B919D4C24DA7A6061) has been confirmed to be malicious by Symantec Security Response. It is a new variant of the W32.Imaut family.
Protection is added in Rapid Release sequence 157041 and above. These new definitions are being posted now to ftp://ftp.symantec.com/public/english_us_canada/antivirus_definitions/norton_antivirus/rapidrelease/sequence/157041/
(Allow some time for them to be posted and replicated to all FTP servers worldwide.)
This article will help to deploy this protection throughout the organization:
How to update definitions for Symantec Endpoint Protection Manager (SEPM) using a .jdb file
Article URL http://www.symantec.com/docs/TECH102607
And, of course, that detection will be added to the set of certified definitions available via LiveUpdate later on today.
Please update this thread with news of whether a scan with these new definitions has successfully removed that threat in your environment! &: )
With thanks and best regards,
Mick
