Non-techie person asks:

There is a .systemRootModeFile in ~/users/me/library.

Is it malware, something horrible?

In the hidden library folder in ~/users/me I have a folder named .f5cd. Inside that is a folder hierarchy of .java/.systemPrefs/_!%... - the last one being a string of about 25 characters - and the folder name is in bold.

Inside that is a file prefs.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<map MAP_XML_VERSION="1.0">
  <entry key="EXPDATE" value="4994"/>
  <entry key="REGVER" value="2"/>

and also within the .systemPrefs folder are two more files .system.lock and .systemRootModFile.

For a non-techie person you dig deep :)...what does your virus scanner says? – Buscar웃 Aug 18 '13 at 9:01
FYI, ~ means your Home folder (/Users/me/) so ~/Users/me/Library actually means /Users/me/Users/me/Library :) ~/Library refers to your Library folder in your Home folder, and so does /Users/me/Library, however combining ~ with /Users/me/Library refers to a completely different folder :) – grgarside Aug 18 '13 at 9:21
@grgarside Thanks for the ~ explanation – user55302 Aug 18 '13 at 9:35
It says it is your JAVA preferences file. the Link will get you to Oracle download. – Buscar웃 Aug 18 '13 at 9:44
Do you have something similar in your system - particularly the .systemRootModFile file? – user55302 Aug 18 '13 at 9:58

.systemRootModFile and the other files you mentioned are part of Java system preferences and are safe. See this thread.
