What is a 'dark web' and should I be worried about it?

A dark web is a part of the internet that is not accessible to regular users, but can be accessed through special software. It is used for illegal activities such as buying and selling drugs, weapons, and other illicit goods. The dark web is often associated with criminal activity and is sometimes referred to as the “deep web”. However, there are legitimate uses of the dark web such as online banking, file sharing, and cryptocurrency trading.
