Configure ClamAV in WHM/cPanel for scan malware in emails

I have server with WHM/cPanel. I have some questions for configure correctly ClamAV and scan the email malware:

1- I installed ClamAV since WHM plugins, I need do anything for Exim scans malware in emails with clamd?. Or this is automatic?.

2- ClamAV is update automatically when update WHM/cPanel?, or I need do anything for update ClamAV?.

Thank you very much. Have a nice day.
