Strange email, but from legitimate website. Is it a virus?

From United States Postal %26lt;usps@usps.com%26gt;

Subject: USPS Delivery Problem NR758803



Attached is a file called: USPSLabel.zip (25kb), and as I click on it, McAfee says it has a virus and asks do I still want to download.



The text is all in an image, which is of the following text, and in poor quality:

"Hello!



Unfortunately we failed to deliver the postal package you have sent on the 19th of September in time because the recipient's address is erroneous.



Please print out the shipment label attached [USPSLabel.doc] and collect the package at our office.



United States Postal Service",



And to the right of that, on the same image, is what looks like an ad, but has no link to click. It says "Change of address? Don't stress. Do it online %26gt;" and a picture of a generic house.



Underneath all of this is text in the body of the email, which is in purple and says "DNC fundraising sets new record, but outside spending still favors GOP Latest Public Eye Headlines - CBS News" with everything from "Latest" to the end in white.



Everything in this email screams "virus", however, the email address it was sent from uses the legitimite USPS website, and I send mail through them and it would be very important if I actually sent one on that day and it got lost. Thoughts?Strange email, but from legitimate website. Is it a virus?
It only LOOKS like it came from USPS. If you know how to read headers of emails, I bet it would tell a completely different story.



I could set up my email program to send emails that look like they come from USPS and unless you read the headers, you'd think it really was from them. I've done this with an eBay address to demonstrate this to my children when I was teaching them about scams.



It's an attempt to infect your computer. Don't open the zip, don't follow any instructions in the email, believe McAfee and just delete the email.
Did you tell the post office to contact you via email on a specific package? Never respond to these emails, contact the post office via telephone or in person if you are concerned.

Here is a very similar UPS email. http://www.techimo.com/forum/security-pr鈥?/a>Strange email, but from legitimate website. Is it a virus?
that is not a valid site, listen to what you read on yahoo. it is a cloned site which will install a virus onto your computer.. please please don't ever believe any thing you receive from a sit that states you have received something free or it was undiliverable.
did you send anything on sept 19th?Strange email, but from legitimate website. Is it a virus?
Any email address can be spoofed, so it is in fact not from a legit source, and since when does the postal service send you a email with a Attachment? This is why users get infected at least you asked about it. My dad doesn't know a thing about computers and never gets infected. I told him don't download from email and don't open emails from users you don't know.This is the rule that's been around for ever. To top it off mcafee told you that it had a virus and you still want to open it. WOW
If you are in any kind of doubt about an email, you should check the origin thoroughly before you click on any links in the mail. You can do this by right-clicking on the mail in your INBOX, and select Properties in the context menu. This will bring up a small window with two tabs on it: General and Details; in the Details tab you will be able to see the ACTUAL sender of the mail, which may be very different from the one it SEEMS to be from. I experience the very same thing as you describe on a daily basis, and i always just delete those mails.

I hope this will help you to better decide what to do about such mails in the future.
