Hello, thank you, but I don't repair my problem, I've tryed the script month ago.
[root@mail ~]# systemctl stop clamd
You have new mail in /var/spool/mail/root
[root@mail ~]# systemctl disable clamd
if I execute
[root@mail ~]# sh /scripts/clamd_fix_100_cpu_usage
Redirecting to /bin/systemctl stop clamd.service
Redirecting to /bin/systemctl stop amavisd.service
Redirecting to /bin/systemctl start clamd.service
Redirecting to /bin/systemctl start amavisd.service
but the cpu is set to 100% and the server is not working well.
