安装ClamAV对centos系统进行病毒查杀

安装ClamAV





1.安装epel源

yum install epel-release





在安装了EPEL源后，运行下面的命令安装ClamAV



# yum install clamav-server clamav-data clamav-update clamav-filesystem clamav clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd -y





2.在两个配置文件/etc/freshclam.conf和/etc/scan.conf中移除“Example”字符





# sed -i -e “s/^Example/#Example/” /etc/freshclam.conf



# sed -i -e “s/^Example/#Example/” /etc/clamd.d/scan.conf



3.手动更新病毒库





# freshclam



病毒库更新时总是链接失败，无法访问到 默认的镜像地址，遂再次进入freshclam.conf 配置文件，在将DatabaseDirectory /var/lib/clamav这一行将之前的注释#删除，然后在系统中创建此文件目录，在 官网下载最新的三个 

main.cvd :http://database.clamav.net/main.cvd



daily.cvd :http://database.clamav.net/daily.cvd

bytecode.cvd :http://database.clamav.net/bytecode.cvd

直接将这三个文件使用迅雷下载，基本上几分钟能下载完(不行就使用旋风)，之后将这三个文件保存到/var/lib/clamav路径下，这是再次运行跟新病毒库命令freshclam 会提示病毒库已更新到最近，接下来就可以执行扫描了



4.对/root目录进行扫描，-r选项表示包含子目录
