Hajime is a type of bad software called malware that can harm people's computers. It sneaks into computers without permission and can cause a lot of problems like stealing personal information or locking people out of their own computers.
Even worse, the people who create Hajime can control it from far away, meaning they can use it to do whatever they want with other people's computers, like using them to spread viruses or spying on the people who use them.
To protect against Hajime, people should make sure their computer has antivirus software installed and they should also be careful about what websites they visit or what emails they open, as these can be ways for malware like Hajime to sneak in.
