What is Scareware?

Scareware is a type of malicious software which aims to deceive users into visiting malware-infested sites, downloading potentially dangerous applications, or purchasing a bogus service. It will appear as legitimate warnings from security services typically in the form of pop-ups or messages from the operating system.

How Scareware Works

Scareware, also known as fraudware, rely on the emotional response of the user. It usually generates pop-ups that resemble error messages from legitimate security software providers. Some may even look like error messages that the operating system generates. These pop-ups will often report a slew of problems on your computer. More often than not, the error messages are enough to frighten the users to have a knee-jerk reaction to resolve the issue immediately.

Just like any malicious software, it tricks you into downloading and installing another dangerous software. Some companies also use this strategy to compel potential users into purchasing their products which are unethical. In 2008, Branch Software and Alpha Red were sued by Microsoft and the Washington attorney general for the creation of Registry Cleaner XP, a known scareware application.

Scareware is a modern iteration of the early forms of online scams. During the early days of the Internet, web pages trick users into calling fraudulent companies that would charge for “technical support.”
