The best Antivirus 2020https://sea.pcmag.com/antivirus/22/the-best-antivirus-protection-for-2020- Windows Defender
You can scan for viruses with windows defender, and you will have the option of removing detected viruses or keeping them (don't know why'd you do that)
Pros: Free, easy to use
Cons: Also might not detect advanced viruses
Windows defender became the main virus and accompanied the second antivirus that I installed. This will be safer with double protection. When Antivirus or Windows Defender is able to ward off any viruses as long as their database is always updated. It is recommended to always be connected to the internet and the database is updated at all times to secure your device.
Honestly, it's much more ideal to recommend Windows Defender and Malwarebytes and nothing else. More choices is certainly better, but if
nearly all of them gather your data, then it's probably best to stick to the lesser evil. They should all work similarly well 99% of the time.
Windows is already gathering your data anyway, so you may as well use their antivirus instead of bringing in another third party to the equation. Malwarebytes has excellent reputation, but while I don't think you should be trusting any company blindly, it's almost necessary if you ocassionally engage in risky behavior. Running them together seem to be the most recommended configuration, and running any more as "backups" is likely counterproductive.
