An Internet worm is like a sneaky digital caterpillar on a mission to munch through the world wide web. It’s a type of malicious software that wriggles its way from one computer to another, leaving chaos in its wake. Unlike viruses, which need a human host to spread, these little critters travel solo, self-replicating and hopping from device to device. They can cause all sorts of trouble, from gobbling up valuable bandwidth to stealing sensitive data. So, if you spot an Internet worm on the loose, it’s time to call in the digital exterminators and protect your precious online garden!
