Number One B is a virus that spreads to other computers by copying its code to other files or programs.
Number One B 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.
Number One B uses the following infection strategies:
- Overwriting: it deletes the content of infected files and substitutes it with its code. Therefore, these files will be unusable and cannot be restored. When users try to open the original file, they will actually be running a copy of the virus.
