Malware? .systemRootModeFile in ~/users/me/library

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 named .java Inside that is a folder
named .systemPrefs Inside that is a folder named _!%....... - a string of
about 25 characters - and the folder name is in bold Inside that is a a
file prefs.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE map SYSTEM "http://java.sun.com/dtd/preferences.dtd">
<map MAP_XML_VERSION="1.0">
<entry key="EXPDATE" value="4994"/>
<entry key="REGVER" value="2"/>
</map>
and also within the .systemPrefs folder are two more files .system.lock
.systemRootModFile
