More Information
W32/Randex-M is a worm which attempts to spread by copying itself to ADMIN$ and C$ network shares with weak passwords. The worm also runs in the background as a service process and allows unauthorised remote access to the computer via IRC channels.
The worm copies itself to the Windows system folder as WINDEV.EXE and adds the following entries to the registry to run itself on system restart:

Microsoft Windows Runtime DLL Services
= C:\<Windows system>\WINDEV.EXE
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Microsoft Windows Runtime DLL Services
