Microsoft Update Impacts Symantec Endpoint Protection Antivirus Software

Thursday, January 11, 2018 - 13:22


On January 3, Microsoft released an update to its Windows operating system to address the Meltdown and Spectre vulnerabilities. Symantec reports that the Microsoft update is affecting some versions of its Symantec Endpoint Protection antivirus software.

Symantec Endpoint Protection version 12.1 RU6 MP5 (12.1.7004.6500) and earlier

  • The Microsoft update may cause Symantec Endpoint Protection to terminate unexpectedly, leaving the computer unprotected.
  • Recommended action: If you are using an older version of Symantec, upgrade to Symantec version 14 as soon as possible. Individual users can download Symantec Endpoint Protection 14 via CSSD’s Software Download Service, and administrators can access managed versions of Symantec Endpoint Protection 14 in the SEP Management Console.

Symantec Endpoint Protection versions 12.1 RU6 MP6 build 7061 (12.1.7061.6600) and later (including Symantec 14)

  • The Microsoft update may cause error messages to appear in the Symantec Endpoint Protection system tray icon. These error messages are harmless and do not affect Symantec Endpoint Protection’s ability to protect your computer.

Symantec is aware of the issue and is planning to release a patch within the next week to resolve it. If you are running a recent version of Symantec Endpoint Protection and do not wish to see the error messages, you may consider waiting to install the Microsoft update until Symantec releases its patch.

Additional information is available on Symantec’s website for Symantec Endpoint Protection version 12 and version 14. Additional information will be posted as it becomes available, so please continue to check for updates.
