Not meaning to rain on the parade, but last Summer you posted BitDefender Internet Security 2015 link of 9 months free. I went to THEIR site, got the code by email, and then downloaded and installed. All on time. When I put in the key in, it came back invalid. I contacted BD, and they responded that it was invalid, and not meant for public release.
I was flabbergasted, because I told them the key was emailed to me by BD! They did however tell me I could buy their 3 PC key for BIS for an exorbitant amount of money. After a week of back and forth wrangling, I finally negotiated them down to a reduced price on a 1 PC key.
So, please be wary of their practices in reality.
