Ransomeware detection.
 

There are so many software for that we can use to protect our system. But I want to know that what are the main steps we need to follow other them a antivirus.

Yes you are right that we need a software for ransomware detection and their removal. But with it we also need to follow some important things that we don't follow. These things are like that we should not allow anybody to connect any kind of device to our computer.We should not keep our modem turn on when it is not in use. Do not download anything from unknown websites.
