安裝ClamAV對centos系統進行病毒查殺

安裝ClamAV


1.安裝epel源
yum install epel-release


在安裝了EPEL源后，運行下面的命令安裝ClamAV

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


2.在兩個配置文件/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.手動更新病毒庫


# freshclam

病毒庫更新時總是鏈接失敗，無法訪問到 默認的鏡像地址，遂再次進入freshclam.conf 配置文件，在將DatabaseDirectory /var/lib/clamav這一行將之前的注釋#刪除，然后在系統中創建此文件目錄，在 官網下載最新的三個 
main.cvd :http://database.clamav.net/main.cvd

daily.cvd :http://database.clamav.net/daily.cvd
bytecode.cvd :http://database.clamav.net/bytecode.cvd
直接將這三個文件使用迅雷下載，基本上幾分鍾能下載完(不行就使用旋風)，之后將這三個文件保存到/var/lib/clamav路徑下，這是再次運行跟新病毒庫命令freshclam 會提示病毒庫已更新到最近，接下來就可以執行掃描了

4.對/root目錄進行掃描，-r選項表示包含子目錄
