Behaviour	Description
WormAutorun	A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Trojan's file once a user opens a drive's folder in Windows Explorer.

Process activity

The Trojan creates the following process(es):

%original file name%.exe:1300
AppLaunch.exe:1824
AppLaunch.exe:1100

The Trojan injects its code into the following process(es):

mscormmc.exe:828
sbscmp10.exe:2012

Mutexes

The following mutexes were created/opened:No objects were found.

File activity

The process AppLaunch.exe:1824 makes changes in the file system.

The Trojan creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Application Data\Winserver.exe (33 bytes)
%Documents and Settings%\%current user%\Application Data\WinUpda.exe (59 bytes)
