See the Symantec support article for additional details and please reach out to Symantec or Norton support if you encounter any issues. Symantec has determined that there is no increased risk of a false positive detection for all in-field versions of Symantec Endpoint Protection and Norton antivirus programs. Symantec has completed its evaluation of the impact of this update and future updates to Windows 7 and Windows 2008 R2. Microsoft has added the following note to KB article 4512506 as of August 28, 2019:

Yesterday I got a comment from German blog reader Hermann informing me, the update hold has been lifted by Microsoft (thanks for that).

Symantec has thus given Microsoft the go-ahead to lift the update blockade. It was determined that the risk of false-positive detection is not increased for all in-field versions of Symantec Endpoint Protection previously installed on systems. Update ban liftedĪ few days ago, Symantec completed its internal assessment of the impact of incorrectly detected August 2019 updates and future updates for Windows 7/Windows 2008 R2. Later, in acomment to the article, German blog reader Andreas confirmed that the updates were offered by Microsoft after updating his Symantec antivirus software (thanks for the feedback). I had addressed this within the blog post Symantec releases a patch for the SHA-2 bug in Windows 7. The distribution for various language versions began already on August 21, 2019. Symantec provides a patchĪ week ago, antivirus vendor Symantec released a patch to fix the update problem under Windows 7 / Windows Server 2008 R2. I reported in the blog post Symantec/Norton blocks Windows Updates (SHA-2).

The reason for this measure was that the security solutions could not cope with the changed signing of Windows updates (since August 2019, these have only been signed with SHA-2). The reason for this was that the antivirus solutions from these vendor supposed to be not compatible with the new updates and could have potentially damaged Windows.Īs a precaution, Microsoft has therefore, in consultation with Symantec, blocked the delivery of updates for affected machines. However, if the users installed antivirus solutions from Norton or Symantec, the delivery of the updates was suspended. As of August 13, 2019, Microsoft released security updates for Windows 7 SP1 (and Windows Server 2008 R2).
