Hi,
Are you the SEPM admin in your organization? If yes, then you can consider to configure following log retention settings:
1> "client log" settings under Policies tab of Clients section
2> "Policies" section -> "Virus and Spyware protection" -> Windows settings -> Advanced options -> Miscellaneous -> "Log Handling" tab -> Log Retention.
