Dúvida sobre o chkrootkit

[Akiyama]

Após sudo chkrootkit deu que tava tudo ok, menos este warning:

Searching for suspicious files and dirs, it may take a while... The following suspicious files and directories were found: 
/usr/lib/pymodules/python2.7/.path /usr/lib/python2.7/dist-packages/PyQt4/uic/widget-plugins/.noinit /usr/lib/jvm/.java-1.6.0-openjdk-amd64.jinfo

O que seria?
