Linux系统下免费防毒软件安装及使用经验

Linux下免费的防毒软件可真是少，不过工夫不负有心人，还是让我找到了一个。

clam antivirus 官方网站： http://clamav.sourceforge.net/
我用的是red hat as 3.所以我就下载了rpm包来装：
http://crash.fce.vutbr.cz/crash-hat/1/clamav/clamav-0.70-1.i386.rpm
安装好了以后，就可以用了。
启动 clamd进程就可以及时防病毒了。
更新病毒用：freshclam
-bash-2.05b# freshclam --help
Clam AntiVirus: freshclam 0.70
