clamav安装方法

ClamAV是一款开源的病毒扫描引擎，可用于检测Windows、Linux等系统上的恶意软件。以下是安装ClamAV的基本步骤，假设你在Ubuntu Linux上操作：

1. **更新包列表**:

   sudo apt update

2. **添加官方仓库** (对于Debian系列):

   sudo apt install apt-transport-https ca-certificates curl gnupg lsb-release
   curl https://www.clamav.net/gpgkeys/current.txt | gpg --dearmor -o /usr/share/keyrings/clamav-archive-keyring.gpg
   echo "deb [arch=amd64 signed-by=/usr/share/keyrings/clamav-archive-keyring.gpg] https://packagecloud.io/clamav/community/debian sid main" | sudo tee /etc/apt/sources.list.d/clamav.list

3. **安装ClamAV**:

   sudo apt-get update
   sudo apt-get install clamav clamav-daemon clamav-scanner

4. **启动和设置服务**:

   sudo systemctl start clamav-daemon
   sudo systemctl enable clamav-daemon

5. **检查更新**:

   freshclam

这将下载并安装最新病毒数据库。如果你想定期自动更新，可以设置cron job。
