/opt에서 애플리케이션을 제거하시겠습니까?

소프트웨어 센터에서 제거 했지만 acroread 9.5.5-1precise1다음 내용은 /opt/Adobe/Reader9그대로 유지된 것 같습니다.

/opt/Adobe/Reader9$ ls *
bin:
acroread

Browser:

Adobe Acrobat Reader를 설치하는 방법을 기억하지 못합니다(소프트웨어 센터를 통해 또는 일부 deb 패키지에서?)

이 파일을 안전하게 삭제할 수 있습니까 /opt/Adobe/Reader9?

/opt/정상적인 상황에서 설치된 소프트웨어를 제거하는 방법은 무엇입니까? 감사해요.
