The WEBlink I gave is in Spanish but please let me translate the fields for you:
NAME
SURNAME
EMAIL
CONFIRM EMAIL
TELEPHONE
Just fill them in and press ENVIAR which means 'SEND' before that don't forget to fill the bot-check box, I got a what is 3+2 math problem.
Once that is done you shall receive a confirmation email with the USERNAME and PASSWORD needed to use the software for 3 Months, I do NOT know yet if this works on the ENGLISH versions of the program as the confirmation page you get after pressing 'SEND' gives a link to download the SPANISH version.
Perhaps someone can confirm, anyway, don't shoot the messenger, and I hope it works for you.
3 months of AV protection ain't much. Why not spend $13 and get a years worth?
