OS 10.5でClamXav 1.1.1を使っていたのですが、ClamXavが起動しなくなってしまったので アンインストールしたいです。検索するとclamavEngineREMOVERでアンインストールできる とのことでしたので実行してみると、下記の表示が。
As you're running OS X 10.4 or higher, the clamav user was not removed because it was created by Apple. The actual engine and any schedules you had set have been removed though
REMOVER has now finished. Drag the ClamXav application to the trash and you're done. You do not need to restart or logout, just close this window.
