W32/Elitper-C is a worm for the Windows platform that targets common Peer to
Peer (P2P) filesharing applications.
Once executed W32/Elitper-C copies itself to the Windows folder with the
filename TASKMANAGER.exe, to the Internet Explorer folder with the filenames
Firewall.exe and WWE DIVAS.exe, and to the Windows Media Player folder with the
filename wmlaunch .exe
W32/Elitper-C also copies itself as XPStartUp to the /Documents and
Settings/All Users/Start Menu/Programs/Startup folder.
In order to be able to run automatically when Windows starts up W32/Elitper-C
sets the registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Firewall
wmlaunch .exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\

Firewall.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\

Screan Saver.exe to the shared folders of the following P2P utilities:
Edonkey2000
BearShare

Morpheus
KaZaA Lite
Kazaa
