Hi,

I have been noticing that the CPU usage in one of my servers increases a lot, from around 24% to 70% and above. I have been checking the crontab and the logs and the logs look quite normal to me. Looking at the maintenance intervals, it looks like the antivirus is the culprit. Is it normal that it goes up that much? I will try to reschedule some other tasks in my crontab if this is normal for the antivirus since I'm getting peaks around 135% CPU usage with some of these when combined with the antivirus.

This server is set up as follows

Operating system Ubuntu 20.04 (64-bit)
Kernel 5.4.0-52-generic
KeyHelp 20.3.1 (Build 2126) Changelog
Web server Apache 2.4.41
PHP PHP 7.4.3
Database server MariaDB 10.5.8
FTP server ProFTPD 1.3.6c
Mail transfer agent Postfix 3.4.13
Mail delivery agent Dovecot 2.3.7.2
Database administration Adminer 4.7.7
Webmail Roundcube 1.4.9
Cryptography OpenSSL 1.1.1f

Here is the last antivirus log.

Hello,

yes the ClamAV consumes a lot of CPU and RAM. This is not unusual and no Bug of Keyhelp.

I see that I forgot to thank you, Florian.

So danke vielen.
