Ransomware is nothing new. You might already have heard about it already, since it is a kind of fraud which can impact anyone and do severe damages. Some ransomware forbid you to access to your computer, while some others do crypt files on your system so that you cannot open them anymore.
No matter the action this kind of malware does, the victim always ends with a frightening message, which tells him to pay a ransom to get the computer access or data back.
People do not react to this message the same way. It all depends on their computer knowledge and on the value of the presumably "lost" data. People get stuck in front of the screen, wondering if they should pay or not. They think of trying to launch anti-virus products, but they are afraid the operation would definitely destroy their data...
Some lucky people do not care at all: they have done regular backup of their important data on an external harddrive. Luckily enough, they disconnect that external harddrive every time they do not use it. Their data is safe, and they will just try to disinfect their computer from the malware. If they cannot do it, well, they will reinstall the whole operating system.
