W32/Esalone-A is a worm for the Windows platform that spreads by coping
itself to the available network drives and by inserting a worm copy into WINZIP
and WINRAR archives. 
Once executed W32/Eightsalone-A copies itself to the Windows folder with the
filename daemon.exe, and in order to be able to run automatically when Windows
starts up W32/Esalone-A sets the registry entry: 
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Daemon
"daemon.exe c daemon2.exe" 
W32/Esalone-A attempts to copy itself as a file called Office_Service.pif
to the <Windows>\Start Menu\Programs\inicio folder. 
W32/Esalone-A copies itself to the root folder of the available network drives
with the filename Readme.txt.exe, and attempts to inserts itself into the ZIP
and RAR archives using the same filename. 
W32/Esalone-A may create a number of files upon run including following:
Infect.drv
Muerte.drv
infectate.reg
