With an aim to make my PC invulnerable to online threats or viruses in a more effective way, I need to activate McAfee antivirus software. But, I know anything about it such as, how to activate it? Where should I go? Whom help should I take? I just want my McAfee activate as soon as possible. Therefore, if anyone out there has any idea about this, please share your views with me. I am eagerly waiting for a reply.
