# 解壓tar -zxvf clamav-0.103.2.tar.gzcd clamav-0.103.2# 安裝到/usr/local/clamav下面./configure --prefix=/usr/local/clamavmake && make install

# 創建組groupadd clamav# 創建用戶并添加組useradd -g clamav clamav# 創建掃掃描出來的病毒存放目錄mkdir /home/clamav/virus# 創建掃描日志目錄mkdir /home/clamav/scan-log# 給用戶組目錄權限chown -R clamav:clamav /home/clamav/

cp  /usr/local/clamav/etc/clamd.conf.sample /usr/local/clamav/etc/clamd.confcp /usr/local/clamav/etc/freshclam.conf.sample /usr/local/clamav/etc/freshclam.conf
