This dangerous program, Win32.Shadow, has a variety of functions depending on the needs of the attacker.  It can be an e-mail flooder, which means it will clog a network or your PC by sending out massive quantities of e-mails.

You can also find it spamming from your PC.  It is able to do this by gaining secret access and then will use your account to send out spam e-mails to countless unsuspecting users.  It is also a backdoor so if entry is gained, it will open up a port on your PC and leave you vulnerable to other malicious attacks.
