Some of the classic giveaways that this is a viruses are seen in the above image. The primary warning flag is that the extension on the attachment uses the three letters "zip". This is short for a "zipped file" and means the contents are compressed and thus of an unknown nature. When we send attachments at the college they usually have the extension "doc" for a Word document or "xls" for an Excel file. No one is using "zip" attachments as far as I know.
The second giveaway is that return address is not anyone I know. An unknown sender would not be suddenly sending me a meaningful attachment out of the blue. I should note that the most advanced forms of viruses now out there can fake the return address and can use a return address of someone you know. We call this a "forged header" because the information on the sender is in the header of the email file. The key giveaway would remain the "zip" file attachment.
The third giveaway is the non-specific, generic, and grammatically incorrect message, "i hope it is not true!" Someone sending an attachment should be far more specific and personal in their message. Quite frankly, one should be suspicious of any attachment that they do not expect to be getting. But even more so if the message is a "generic" message such as the above.
One might think that the message "Mozilla thinks this is junk mail" is a fourth indicator that this is a virus, but that message is specific to the email and browser package I use at home to help protect my home system.
On a daily basis our IT crew is battling the viruses and worms that seek to evade our protective systems. Ultimately, however, their good fight is doomed to failure without our help as computer users. We will have to learn to recognize threats and respond appropriately.
In the above situation, delete the email and then empty the trash or recycling bin in your email package to rid yourself of the dangerous email. If you need more information, please do not hesitate to contact me.
