Symantec Endpoint Protection Cloud (SEPC) clients scan Microsoft SQL Server files and folders by default.
To minimize the impact of SEPC client antivirus scans, exclude the folders housing Microsoft SQL Server database files. For more information on configuring exclusions, see Configuring security policy settings and Scan exclusion settings.
Note: It is necessary to exclude the folders containing these files for maximum effectiveness.
