ClamAV 安装使用

01. 设置阿里 yum 源

1wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

02. 安装 clamav

1yum install -y clamav

03. 更新病毒库


04. 扫描病毒

1mkdir virus_temp
2clamscan -r -i / -l clamscan.log --move virus_temp/

  扫描根目录下所有文件,-r 所有文件,-i 只输出感染文件,-l 指定扫描日志,--move 将病毒移动到指定目录
