In order to mask the fact that it is propagating, it pauses before starting to infect the next P2P network.
Once a P2P network is infected, the worm will search for folders with the following names:
share* download* music* mp3*
Every ten minutes, the worm launches an infection routine affecting P2P networks.
It creates a BAT file on disk under a random name. This file, when launched, is designed to track when a user ends a process. When this happens, the BAT file will delete the worm's executable file from the disk.
The worm checks the system registry value every second.
It downloads and launches files from the Internet.
How it manifests itself in the systemIn order to baffle users, depending on the name of the file the following error messages may be displayed during work with the computer:
Key Generator
-------------
Unable to load geneneration tables.
Check tables.gen is in current directory.
Crack Engine
------------
Unable to patch file.',0Ah,'Must be in same folder
The worm also connects to a number of IRC channels to inform the author of the worm about infected machines.
