the hacker is actually an expert who uses his skills in crime. for the case of ransomeware it is already familiar. they use these weapons to ask for a ransom in the form of bitcoin to open access to the computer they hacked. The key is to frequently update the antivirus and surf well. Leave suspicious websites so that there are no gaps for them to access your computer.
