Issue/Introduction

A file has been created in the root of Symantec Endpoint Protection (SEP)'s VirusDefs folder. The file has the .db extension. It may be seen as Cat.db or umcat_01.db.  What is the purpose of this file?

 

Resolution

This file is from the core component SymVT. SymVT is designed to verify known trusted files. In order to do so it creates a catalog database for lookups of known signed files. The file is placed one directory up from the dated definitions folder so that definitions refresh wouldn’t result in requiring a re-creation of the entire database.

There is no need for any end user interaction with this file.
