CERN replaces Symantec with Forefront

CERN - the European Organization for Nuclear Research - recently announced in its computing newsletter that it is replacing Symantec with Forefront Client Security to protect PCs on its network.  Why?  From the newsletter:

By the end of this year, all NICE PCs will have MS Forefront Client Security installed. This new anti-virus and anti-malware application will replace the current anti-virus product from Symantec. The reasons for this change include the small footprint of the client application, excellent response times for pattern updates and very good integration with the existing NICE infrastructure.
