I purchase it from a local elctronic store. I experincer a lot of problems installing it. You have to use the number on the card and go online to download it. I had to contact their tect department and get help installing it. It is not as easy as McAfee claim on the instructions in the box.

I ordered this based on the details stating "1 disc". Pretty standard. Upon arrival, it's not in disc form at all. Instead it's a credit card shaped thing with a product key code, stating to use you must access the internet & enter the code to download the software. I have a virus I'm trying to eliminate which is not allowing me to go online, which is why I made sure it stated IN DISC FORM when I ordered! Now after waiting for incredibly slow delivery for what should have been mailed in a padded mailer & arrived in 2-3 days, I have to return it & find another product, and am still offline on my main computer. The product may actually work great - I was counting on that, but I'll never know. Very frustrated right now.
