Antivirus software is like a superhero that protects your computer from bad guys called viruses.
Just like how we wear masks to prevent getting sick and wash our hands to remove any germs we may have touched, antivirus software scans your computer for any viruses that may be lurking around, and removes them from your computer, making it safe for you to use again.
It does this by constantly checking for files and programs that may be harmful and stopping them from infecting your computer. Think of it like a lock on your door that keeps unwanted guests from getting into your house.
So, to make sure your computer stays safe from those bad guys called viruses, you need an antivirus software program like a superhero to protect it!
