Ryuk (ransomware)

Okay, so let's talk about Ryuk - it's a type of computer virus called ransomware. Think of it like a sneaky little monster that gets into your computer and blocks you from using it.

What does it do?

Well, Ryuk encrypts (or scrambles) all of the important files on your computer so you can't open them. It's like putting a big lock on your favorite toy box so you can't get your toys out. The only way to unlock your files is to get a special key, which the people who made Ryuk have. They will only give you the key if you pay them a lot of money, like thousands and thousands of dollars.

Why do they do this?

Because they want to make money, of course. They know that if they lock up all of your important files and you can't get them back without paying them a lot of money, you might just give in and pay them.

How can you prevent Ryuk?

Well, you can do a few things to be safe from Ryuk. First, be careful about opening email attachments that you're not expecting or that come from an unknown sender. Sometimes Ryuk comes in an email attachment that looks harmless, but when you open it, the virus gets into your computer. Second, make sure you have a good antivirus program on your computer to protect you from attacks like Ryuk. Finally, always keep a backup of your important files somewhere safe, like on an external hard drive or in the cloud, so even if Ryuk does lock up your computer, you won't lose all of your files forever.
