Rabad is actually an acronym that stands for Remote Access Trojan (RAT) Builder and Downloader. This might sound complicated, but basically it's a type of computer program that is used by bad people to hack into other people's computers and steal their information or control their computer without them knowing.
Think of it like a secret spy program that someone sneaks onto your computer while you're not looking. They can use it to watch everything you do on your computer, steal your passwords, or even take control of your computer and make it do things you don't want it to do.
To protect yourself from Rabad or other types of computer viruses, it's important to have good antivirus software on your computer and make sure to never download anything from suspicious websites or email attachments from people you don't know.
