Because the virus pulls addresses from your harddrive to resend itself out, the address that the message says it is from and the address it is being sent to are both fake and neither are actually legitimate peices of correspondence between either person. You may receive a message stating that you attempted to send this virus when in fact you didnt, and you may receive a message containing this virus from someone who in actuality did not send it to you.
The E-mail message will have one of the subject tag lines listed below.

Further details about the history of this virus and its effects is available from Symantec. Although this virus has the potential to copy secure information from your computer and send it back to the virus creator, its most notable cause of harm is the annoyance of having to delete dozens if not hundreds of messages from your E-mail client on a daily basis.
If you think that you are infected you should update your anti-virus software immediately and then run a full system scan. For more information on virus updates and anti-virus software, visit our Virus Information section.
