Bugbear is a Windows mass mailer, spreading itself in infected e-mail attachments, sometimes executing the attachment automatically. It also tries to spread through open Windows fileshares. A side effect of this is that the worm sometimes prints massive amounts of nonsense text on network printers.
The worm also attempts to terminate the processes of various antivirus and firewall programs. Once a machine is infected, it can be remotely controlled via a graphical backdoor, allowing the hacker to steal and delete information from affected computers.
