Support for Symantec AntiVirus Corporate Edition (SAV) 10.x has ended
Beginning June 18, 2013, support for Symantec Antivirus Corporate Edition 10 has been discontinued It is significant that LiveUpdate will continue to run without visible errors, although there will be no new signatures to download. The antivirus itself will also notify about outdated databases immediately (not earlier than in a month) and only when the computer is restarted. In particular, I only after six weeks found that the anti-virus has outdated signatures. Check the systems you are servicing and the users you are consulting for obsolete and non-updated antivirus.
PS Maybe this news will be a bit late, but I have not yet met.
