Google Chrome was updated to version 78 a few days ago, and some users experienced crashes instead of the promised features.

This crash occurs when the web browser boots on systems with an outdated version of Symantec Endpoint Protection (SEP).

If you see this behavior on a workstation or during a connection provided from your workstation, it may be due to a known incompatibility between Chrome and older versions of Symantec Endpoint Protection. You can contact your IT department for additional assistance and share the information below:

You must upgrade Symantec Endpoint Protection to version 14.2 or later. You can also disable the additional protection that causes this incompatibility by using Chrome’s RendererCodeIntegrityEnabled policy.

If you observe this behavior on a home computer, additional information will help our team investigate further. If you are able to do so, please respond to this thread and provide the name and version number of the anti-virus software you are using on your computer. Please note that the responses are public, so please do not provide any personal information.

Workaround from Symantec

For all other cases, a workaround is to add an application control exception for Google Chrome and Microsoft Edge Chromium executables (Chrome.exe and MSEdge.exe).

An alternative is to run Chrome with code integrity disabled, which can be done in two ways:

Chrome.exe –disable-features=RendererCodeIntegrity
or by setting a registry key to 0:

Key: HKLM\Software\Policies\Google\Chrome
Name: RendererCodeIntegrityEnabled
Type: DWORD (32-b

Symantec Endpoint Protection Update
