Just imagine it: a hacker makes your unique, irreplaceable computer files inaccessible and you can only get them back if you pay a ransom.
Think how many valuable files you have on your computer: family photos, large reports, your finances, research results, to name but a few. What would you do without them? Files like this make an ideal ransomware target for hackers. They remain on your computer but they are locked. When you try to open them, or sometimes even when you start up your computer, you get a message telling you that you have to pay a ransom before you can do so. But even if you do pay, you won’t always get your files back.
It's difficult to fully protect yourself from these kinds of attacks, and once you've fallen victim to one, all you can do is pay up or erase the entire content of your hard disk. Luckily you can limit the consequences of this by making sure that you always have an up-to-date backup.
Prevent your data from being kidnapped.
