clamavはopen source antivirus engine です。 データベースをアップデートするコマンドはfreshclamです。最近さっぱりアップデートされないので、調べてみました。
freshclamを実行した結果は以下の通りです。”host 10″という意味不明なホストに接続できないと言っています。

これの解決法は Debian Bug report logs – #748670 clamav-freshclam: doesn’t upgrade anymore にあります。具体的には /etc/clamav/freshclam.conf 中の
PrivateMirror 10
が問題の箇所で、この行を消せば良いようです。私は上記のページの通り ‘dpkg-reconfigure clamav-freshclam’ を実行し、remove the ’10’, when asked for the ‘Private mirror for freshclam’ を行いました。
