Answer
GMS Anti-Virus failed to update the signature files correctly. For some reason, the new signature files and/or code could not be copied over the old signature files and/or code.
In this case, the file Undefined could not be copied over Undefined. The operating system gave the error Undefined.
You are not currently protected by the latest virus signature files. In order to get protection, you should stop GMS and copy the files as indicated in the error message and restart GMS. If you have a support contract, please contact Gordano Support to report this issue.
