I have encoutered in all hosts a file with 851,7KB with many names, all of these files are the same file inside a WinRar file named Video.exe. The file is a Troian Horse/Backdoor.
The video.exe obstruct the load of taskmanager of Windows making impossible stoping the task and use the Limewire how a downloader of porn arquives in the "Documents and Settings/complete" folder. If you exit Limewire he load automatic and the download of porn arquives continue.
The proliferation of this file indicates a big number of machines with infection.
