If you have not been receiving UPS notifications, you most likely will be as this one of the latest scam email schemes going around. I have been getting them for the last few days now. See the article link below for more details, but the attachment carries a nasty package of fake antivirus software.
This is a good reminder to be wary of unsolicited emails and always be aware of what you are doing when opening attachments of any kind. Even if you are expecting a package from one of these services, there are a few things in the email that should alert you.
1) The ones I got were sent out to many people in the “To” address line; how could this be if it is personalized for me?
2) No notification service would send out a “.zip” file for you to unzip; they would just give you the info in the body of the email.
3) The “From” address was a little suspicious, even if some of them did come from letters-numbers@ups.com
