Whiter.F is a Trojan that creates a text file called WXP in the root directory of the C: drive. This file contains the phrase You did a piracy, you deserve it.
Whiter.F replaces all the files in the hard drive with the text file it has created, and then deletes them. This causes the affected computer to stop functioning.
Furthermore, even if the user attemtps to recover the hard drive data using a special tool, the files recovered will not be the original, and they will only contain the aforementioned phrase.
Whiter.F does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.>
