The hyped-up 'Pokey' virus doesn't seem to be widespread.
Pikachu is an Internet worm that spreads itself as an executable file attachment using Microsoft Outlook. The worm was written in Visual Basic 6 and it requires VB6 libraries to be present in a system to run.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
The worm usually arrives in an email message that looks like that:
Subject: Pikachu Pokemon Body: Great Friend! Pikachu from Pokemon Theme have some friendly words to say. Visit Pikachu at http://www.pikachu.com See you.
The worm is attached to this message as the PIKACHUPOKEMON.EXE file. The file has an icon resembling Pikachu character.
When a user clicks on the attachment, the worm is activated. It shows a dialog with Pikachu image and the following text:
Between millions of people around the world i found you. Don't forget to remember this day every time MY FRIEND! Visit us at http://www.pikachu.com
The dialog that the worm shows upon activation looks like that:
Then the worm accesses Outlook address book and sends messages with its body attached to everyone in this address book.
The worm has a dangerous payload. It adds several commands to AUTOEXEC.BAT file that will delete \Windows\ and \Windows\System\ folders when a system is restarted. A system asks confirmation to delete files, so if a user doesn't press 'Y', his files are not deleted.
