Use the Symantec Power Eraser and scan the system. This utility is more aggressive in catching unknown malware.

If SPE doesn't find anything than you may need to try a third party tool such as malwarebytes or hitman pro. If something is found, than you can submit to Symantec response so definitions can be created.

Have you submitted the winlogon.exe file to security response yet?

Please click the "Mark as solution" link at bottom left on the post that best answers your question. This will benefit admins looking for a solution to the same problem.

This article may help:

Also: if you have SEP 12.1, you can increase the sensitivity of the Insight-based heuristics.  That will make SEP 12.1 more aggressive in its approach to unknown files.
 

With thanks and best regards,

Hello,

You could try running the SERT Utility on one of the client machines.

If you have access to Fileconnect, the SERT (Symantec Endpoint Recovery Tool) is useful in situations where computers are too heavily infected for the Symantec Endpoint Protection client installed upon them to clean effectively.

Symantec Endpoint Recovery Tool (SERT)

The Consumer version of this tool is the Norton Bootable Recovery Tool.  

The tool is free, so there is no need for a Fileconnect account to download the software.

You could also try working on the steps provided below on collecting the suspicious files and submitting the same to the Symantec Security Response Team.

Using Symantec Help (SymHelp) Tool, how do we Collect the Suspicious Files and Submit the same to Symantec Security Response Team.

I would also recommend you to make sure you create a case with Symantec Technical Support.

You could either Create a Case OR contact Symantec Technical Support.
