#先停止freshclam systemctl stop clamav-freshclam.service
#再更新 /usr/local/clamav/bin/freshclam (根据网络质量确定更新时长) 或者 cd /usr/local/clamav/share/clamav
wget http://database.clamav.net/main.cvd

说明:如果在手动更新病毒库的时候遇到错误,此时就要删除掉旧的镜像地址文件#rm -f /var/lib/clamav/mirrors.dat,再手动更新一次病毒库。
clamdscan:
clamdscan /usr
clamscan:
扫描参数:
#扫描所有文件并且显示有问题的文件的扫描结果
clamscan -r --bell -i /
#只显示找到的病毒信息
clamscan --no-summary -ri /tmp
#扫描home
clamscan --infected --remove --recursive /home
#让服务器每天晚上定时更新和杀毒,保存杀毒日志,crontab文件如下:
1 3 * * * /usr/local/clamav/bin/freshclam --quiet
20 3 * * * /usr/local/clamav/bin/clamscan -r /home --remove -l /var/log/clamscan.log
可以用下面这个命令,只显示找到的病毒信息

clamscan --no-summary -ri /tmp -r 递归扫描子目录 -i 只显示发现的病毒文件 --no-summary 不显示统计信息 |
