Wolf.A is a virus that spreads to other computers by copying its code to other files or programs.
Wolf.A uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
- File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.

- Companion: it renames files on the infected computer. This virus also makes copies of itself, and assigns them the original names of the files it has renamed. When users try to open the original file, they will actually be running a copy of the virus.
