Consumers are being warned about a scam email promising a $500 Myer gift card, which may actually conceal a virus designed to access their bank details.
NSW Fair Trading Minister Virginia Judge says the scam email from "Shoppers Saving Centre" asks people to participate in a survey in return for the gift card.
The Fair Trading department has received reports that people who took part in the survey never received the gift card.
"This appears to be a phishing scam designed to obtain consumer's internet provider addresses so that an embedded virus can access their banking details," Ms Judge said in a statement on Tuesday.
Myer has told the department it has no association with "Shoppers Saving Centre".
Ms Judge says anyone who receives the email should delete it immediately.
