The common user experience when it comes to ransomware looks like this: you open a website then accidentally download and install a piece of software. You might even not notice that you’ve done that. For some time nothing happens and suddenly you see a notification that all your files are encrypted by a Trojan that wants money to return them back. You check to see if it’s true and see: all your files refuse to open. You also see that they are updated with the ominous .crypt extension.
