Some people want to know what is the "best antivirus", I am a little disappointed and it's difficult for me to answer this question. I think Windows Defender is good but I can't give arguments. How can I answer this?
Normally when doing a product evaluation you look at multiple factors:
- What do you seek as minimum features to achieve the desired outcome (e.g. centrally managed, easy deployment, offline/online updates, HIDS/HIPS support, file integrity monitoring, etc...)
- For AV specifically you want to look at coverage, this can be seen in most comparison websites (e.g. after submitting x amount of samples, how many were detected)
- How fast do they update their sources
- What's the cost
This is what I would normally put as part of an evaluation for AV.
