It's a valid question, but a great example of how to get a valid question closed as quickly as possible. Read the question from the perspective of an average computer user (which is whom Super User is
trying to appeal to), and you'll see very quickly that the question was asked in a way to try and sway your opinion before the OP even asked what he/she wanted to. We take security questions seriously here on Super User, and I feel that any question that prompts you to
prove why you need an antivirus software is of bad form. Start with the most security, and reduce it where needed. —
