This attachment contains the Virus.
There are even emails pretend to be Upgrades from Symantec Antivirus, Microsoft Security patches etc,
What it is common to all of them is attachments, and these attachments contain the Viruses.
Many of these attachments pretend to be ?promised passwords?, Screen savers?, "security patches." Claim to be ?Your Text?, ?Your File?
The First Rule of email:?Never open an attachment unless it was agreed upon?. Agreed Upon means that a person that you know send you first a trusted email that tells you that he is going to send an Attachment.
