Computer worm

A computer worm is like a tiny bug that crawls into your computer through the internet. Once inside, it makes copies of itself and starts spreading to other computers on the internet, just like germs can spread from person to person.

The worm can do bad things to your computer, like slowing it down, deleting important files, or even stealing your personal information.

Think of it like a worm that finds its way into an apple, and then starts making copies of itself inside the apple. It can then spread to other apples in the orchard, making them sick too.

So, just like you need to wash your hands regularly to avoid getting sick, you also need to be careful when using the internet and make sure your computer has good antivirus software to protect it from worms and other nasty bugs.
