E-mails claiming to come from the United States Postal Service (USPS) are currently being used to deliver a Trojan downloader.

"The spam emails pose as failed delivery notifications and bear a subject of 'Post Express Information. Your package is available for pick up,'" writes Softpedia's Lucian Constantin.

"The attachment is called Post_Express_Label_ID_[number].zip and contains a malicious executable of the same name," Constantin writes. "If run, the exe file installs a trojan downloader on the system which, according to the results of a Virus Total scan, has a low detection rate among antivirus products."
