symantec liveupdate fail in win7

[Anderson Hsu]

Hi,
Why Symantec (version 14.3 RU4, 14.3.7388.4000) can not liveupdate virus
definition in win7, but can liveupdate in win10? Thanks.

Hi Anderson,

Thanks for using the Broadcom Community!

To better assist you with your issue please open a Support case. 

The issue could have a variety of different causes.  

However, if I were to guess it would be that your Win 7 devices are limited to downloading content from Live Update and this stopped working because they don't have TLS 1.2 support. 

For more information see this link:

If this is the case then you'll need to upgrade your OS to a version that supports TLS 1.2. 

Thanks,

Russ_V

Hi!

Suggestion:
- First, confirm if the MS KB3140245 update is installed,
- then run the MS MicrosoftEasyFix51044.msi tool.

You can find the details here:
