With the email address you registered on forums , I do see that you have subscribed for McAfee Antivirus Plus .
So, all you have to do is , logon to http://us.mcafee.com/root/login.asp and install the products
If you don’t remember the password, use the forgot password option from there that should help you get started .
This time I tried to install it and it didnt even ask for my email it just came up and said: "We're sorry, but there are no programs that you can install from this Mcafee account. Please login with another Mcafee account and try again".
I managed to get it to install and activate with the retail cd but I recall being at this same place before then having it start to ask to be activated again. We'll see what happenes.
