W32/Myfip-H is a worm that spreads using network shares that are either 
unprotected or protected only by weak passwords. 
The worm copies itself to the file kernel32dll.exe in the Windows system 
folder. 
The worm attempts to register itself as a service process with the ServiceName 
and DisplayName "Distributed Link Tracking Extensions". 
W32/Myfip-H creates the following registry entry: 
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Distributed File System
kernel32dll.exe 
W32/Myfip-H builds a list of all filenames whose extension is one of PDF, DOC, 
DWG, SCH, PCB, DWT, DWF and MAX and whose path does not contain any of the 
following strings: 
Winnt
Windows
I386
Program Files
All Users
Recycler
System Volume Information
Inetpub
Documents and Settings
Wutemp
My Music 
The worm then sends the contents of each file to a preconfigured IP address. 

This IDE file also includes detection for:
