Scared of ransomware attacks?

[underdoq]

I think with doing more researcher about the origin and comments about files you download to your PC you will prevent most infections without any software, then Microsoft Defender is enough protection today, there's is no need for other software (Malwarebytes scan here and there, yes!).
But i think if there is person with enough capacity to bypass most security , we could be all infected right now without even knowing it. If someone is determined to that stuff, i think he can mass access pc's that are internet connected and use them for his purpose.
