Ubuntu 22.04下ClamAV 1.4 安装与配置实时监控

安装：

sudo apt install clamav clamav-daemon

GUI:

sudo apt install clamtk

配置文件在 /etc/clamav/下

clamd.conf 

freshclam.conf

可以调用图形界面修改配置：

sudo dpkg-reconfigure clamav-daemon

一般情况下安装完病毒库会自动更新，如果要启用实时监控需要单独配置：

在clamd.conf最后单独加入:

OnAccessExcludeUname clamav
OnAccessIncludePath /home/pgciq/Downloads
OnAccessPrevention yes

然后启动实时监控：

sudo systemctl enable clamav-clamonacc.service
sudo systemctl start clamav-clamonacc.service

检查后台服务及实时监控状态：

sudo systemctl status clamav-clamonacc.service
