查看使用帮助：
/home/clamav/clamav/bin/clamscan -h

下面举两条例子：
扫描某个目录（如：/home）:
clamscan -r /home

扫描服务器上的所有文件并且显示所有的文件的扫描结果
 clamscan -r /

扫描服务器上的所有文件并且显示有问题的文件的扫描结果
clamscan -r --bell -i /

可以做个定时任务让他定时更新病毒库，定时扫描查毒。比如：
crontab -e

#每周日一点更新病毒库
0 1 * * 7 /home/clamav/clamav/bin/freshclam
#每周一到周六一点查毒
0 1 * * 1-6 /home/clamav/clamav/bin/clamscan -r --bell -i / -l /home/clamav/clamav/logs/clamd.log
