very general and superficial recommendations:

• Examine the logs prior to change of file
• review of programme withdrawal last (details) $ man last)
• Checking of control amounts of files in packages (package) http://manpages.ubuntu.com/manpages/hardy/ru/man1/debsums.1.html )
• " File tracking " using the mechanism inotify (e.g. by https://packages.debian.org/ru/sid/incron )
