《ClamAV》
《clamtk, 按需病毒扫描器，用于Linux系统，易于使用，重量轻》
官方下载离线安装包：
http://www.clamav.net/downloads
https://github.com/dave-theunsub/clamtk
https://github.com/dave-theunsub/clamtk-gnome
目的：
安装Linux下使用ClamAV，主要还是扫描Windows病毒，毕竟在Windows下干扰太多了。
Deepin15.11下在线安装ClamAV：
sudo apt-get install clamav-daemon clamav-docs libclamunrar7注：
1、clamav-daemon，clamav-daemon将会建立一个名为'clamav'的帐户。如果你安装clamav，要自己建账户。推荐
clamav-docs，ClamAV说明文档。可选
libclamunrar7，支持ClamAV扫描压缩的RAR文件。推荐
其他依赖在apt-get install 时会自动安装。
2、默认配置文件位置：
/etc/clamav/clam.conf
/etc/clamav/freshclam.conf
3、默认log文件位置(需要root权限写入)：
/var/log/clamav/clamav.log
/var/log/clamav/freshclam.log
4、缺点：不能显示进度百分比。
安装后必须更新：
sudo freshclam使用命令扫描：
clamscan -r /指定路径
clamscan -r --bell -i /指定路径
clamscan -r --bell -i /指定路径 -l /指定log文件位置
clamscan -r --bell -i -o /指定路径 -l /指定log文件位置-r 递归扫描
--bell 报警声
-i 只显示受感染的文件
-l 指定log文件位置(需要提前创建文件)
-o 跳过扫描OK的文件
--remove 删除被感染文件(不推荐)
--move 移动病毒文件至指定目录
--quiet 只输出错误消息
--unzip(unrar)解压压缩文件扫描
注意：检查log文件写入是否需要root权限写入，需要就在命令前加sudo。
安装第三方GUI——ClamTK：
sudo apt-get install clamtk clamtk-gnome使用ClamTK扫描：
sudo clamtk注：
1、默认log文件需要root权限写入，所以要用root权限运行ClamTK。
2、clamtk-gnome安装后需重启Nautilus，在深度文件管理器无法生效。
3、优点：可以显示扫描数量和百分比。
缺点：sudo扫描后，历史也没有记录。一个窗口只能执行一个扫描。不能显示细节。

1、有些Windows下Avast、Symantec没报的，ClamAV却报了，只能说结果仅供参考。
