I guarantee (without checking) the majority of votes will be Avira Free Antivirus.
Why?
- Better detection than Windows Defender
- Avira Protection Cloud to upload unknown samples to their cloud database (ie. zero-day protection)
- Lighter on system resources
- Faster at removing infected items
@kuttan It would be good to know who will be using the computer, is it for yourself who is knowledgeable and aware of warez-risks, or another person who isn't? Otherwise see my first sentence.
In my opinion, both are equal.
