A malware infected email claims that several major supermarkets have collaborated to offer customers an all-in-one shopping voucher worth £30 [12 September 2012]
The message is not a legitimate offer and there is no such voucher associated with the supermarket chains.
Recipients are instructed to click a link in the email to read more information and download the voucher for printing. A second link in the message supposedly allows recipients to opt out of receiving further such marketing emails.
If you click on the links you will find that a .zip file is downloaded onto your computer. The zip file contains a .exe file that, if opened, will install a Trojan onto your machine. The virus dupes users into believing it is harmless by calling itself "voucher.pdf.exe".
