Millions of people eat at McDonald’s everyday - it’s a fact. Trying to reproduce the McDonald’s graphics, scammers advertise a free meal at the most popular fast-food chain in the world.

The recipients of the message have to open the coupon attached to the email and print it, so they can bring it to the store to redeem their meal.

The only problem is, the attachment contains a very serious virus. It could be malware or a keylogger.

How to avoid: you know what they say, there is no such thing as a free lunch. Make sure you know how to differentiate the criminals’ emails from the authentic ones-- look for misspells in the company’s name (for example, McDonalds instead of McDonald’s) and in the domain name of the email address (it could be spelled mcdonallds.com). When in doubt, go to the official website by typing it yourself in the browser.
