Things to watch out for
Not be confused with cookies that you eat, cookies is a packet of data that tracks what you search on the internet and can use this info to suggest things that are similar to what you searched previously. For example Youtube use it to suggest certain videos that are similar. Amazon also uses this to suggest products that are similar to what you have bought before. They do this covertly because they don't get your permission to track what you search and use it.
Again not to be confused with worms you find in the ground, worms is a Malware software that replicates itself in order to spread to other computers. It often uses a computer network to spread itself.
