If you've received an email in your inbox telling you that your wire transfer has been cancelled, take care - as it's the latest attempt by online criminals to infect the general public's Windows computers.
Brits (as opposed to Americans) probably won't be as likely to be duped by the spammed-out messages which use the US spelling of "canceled" in the subject line, and claim to come from the Federal Reserve.
The Wire transfer , recently sent from your bank account , was not processed by the FedWire.
Transfer details attached to the letter.

Attached to the emails is a file called PAYMENT RECEIPT 30-04-2013-GBK-75.zip which Sophos products detect as containing the Troj/Zbot-EVX Trojan horse, designed to hijack your computer and - potentially - plunder your finances and steal private information.
Of course, the danger is that unsuspecting computer users will open the malicious email attachment even if they haven't recently tried to wire some cash.
The social engineering trap used in this attack takes advantage of people's natural curiousity, which - in many cases - will drive them to investigate the file even if alarm bells should be ringing.
Up-to-date anti-virus software and software patches can help protect your computer, but the real lesson that internet users need to learn is to not be so trusting of unsolicited emails that arrive out of the blue in their inbox.Follow @gcluley
