Every time you enter the URL (address) of a website, such as into the address bar of your browser, the URL is translated to the IP address (Internet Protocol address) of the web server where the web page that you want to access is stored.

Some malicious programs can stealthily redirect you from an authentic URL to an inauthentic website to acquire sensitive information such as usernames, passwords, and credit card details.
