Bagle is a mass-mailing worm designed to copy itself to the Windows system directory and open a backdoor. Bagle spreads itself as an email attachment and sends messages with the subject 'Hi' and random EXE attachment names. Once executed, Bagle will secretly install a backdoor, which can be used by the remote attacker to get the full control over infected computer.
