使用代理身份验证的 clamav 更新问题
clamav update issue using proxy authentication
我在使用代理身份验证更新 clamav 时遇到问题。我在 /etc/clamav/freshclam.conf 中添加了代理信息，如下所示：-
# Proxy Setup
HTTPProxyServer myproxy
HTTPProxyPort 3128
HTTPProxyUsername proxyuser
HTTPProxyPassword proxypass
保存文件时，我收到以下警告。
WARNING: Insecure permissions (for HTTPProxyPassword): /etc/clamav/freshclam.conf must have no more than 0700 permissions.
所以我按照建议将文件权限更改为700。现在我收到一个错误。
ERROR: Can't open/parse the config file /etc/clamav/freshclam.conf
如果我回滚权限，它会给我警告。如果我申请权限，我会收到错误消息，无论哪种情况，我都无法让 clamav 更新。
只有当我删除它尝试连接的身份验证时（我必须将权限回滚到默认的 444），并且出现以下错误：-

我已经尝试了所有我能找到的。我也重新配置了
> dpkg-reconfigure clamav-freshclam
还是一样的结果。我看到这个 clamav 的方式是使用代理连接。
