The last update of this worm was seen in August 2009. Many versions of this worm had been troubling several computers since more than a year. The worm mainly targets the "C:\WINDOWS\System" directory. When executed first, it drops several list of files in various unknown formats such as fne, run ,edt, fnr, etc. It also adds a few dlls to the folder and edits the registry such that it is run at every system Start up. A file with name "XP-E9EF8E2E.EXE" is added to the registry as well as the %System% directory and this is the main file that affects your system. When a Removable disk is detected, the worm immediately adds an autorun.inf to the drive along with a file named "Recycled.exe" which consists of the code to launch "XP-E9EF8E2E.EXE". Not only that, it also adds several unknown characters like "´ò¿ª(&O)" and "ä¯ÀÀ(&B)" to the autorun file such that these symbols are added to the options when you right-click the removable disk. In addition to all this, the worm also adds a shortcut of the file to "C:\Documents and Settings\User\Start Menu\Programs\Startup\" thus assuring the launch of "XP-E9EF8E2E.EXE" at start up.
