Browser security

Browser security is like a door that keeps bad things out of your computer. It's like a guard who won't let anything harmful come in. When you are online, your browser is like a locked door — it keeps hackers, viruses, and other online threats from coming in and stealing your information or damaging your computer. Your browser also helps make sure the websites you visit are safe. It does this by checking the website to make sure it’s secure and up-to-date.
