Hi guys! I just download the McAfee antivirus and it's working great. I currently have the 30 day trial, it will expire on July 10. I'm thinking of buying it next week via retailers (you know, those in the game shops) and here is my question; if I download it successfully, can I use my registered antivirus account for McAfee on it? If I can, will the newly bought subscription stack with the trial days, or will it replace the trial date?
