You have likely been alerted by popups while browsing the web. These, often flashing, advertisements claim your computer has more than a thousand errors requiring urgent attention to fix. Perhaps helpfully, these popups offer a solution to cure your computer with a click of the mouse. Buttons marked “fix now” appear to offer a simple fix to all your computer troubles.
These advertisements are often described as Registry Cleaners, or by a few other names that attempt to convince the user they will somehow clean or improve their home PC. Within the IT industry they are known as “scareware”. They are software designed to convince you that your computer has problems it might not have.
