My job is with a Madison, Wisconsin television station as a reporter. I don't make orders for products on behalf of the station, but even if I did, I would not click on a link from a sender in Brazil who I've never heard of before.
I guess they could be sending me coffee and as the father of three young kids, that's always welcome, but Rule No. 1 when preventing viruses from infecting your computer and exposing yourself to identity theft is to always refrain from opening links sent by people you don't know.
Here are some basics on that topic from the U.S. Department of Homeland Security: http://www.us-cert.gov/publications/virus-basics
Please don't click on links like the kind posted below. I have no idea where it goes, but I'm guessing I don't want to know.
