According to Norton, spyware is the most common threat on the internet. Moreover, spyware is difficult to detect. Spyware programs threaten individuals as well as businesses. It is malware that infects a device and gathers information, such as passwords, PINs, usernames, social security numbers, bank account numbers, birth dates, and security codes.

The malware runs in hidden mode, so the user does not know if some spyware is present on their device. Various types of spyware infect devices, including laptops, computers, mobile phones, and tablets. Mobile spyware such as Xnspy has a keylogger that detects the keystrokes on the device. Hence, certain spyware can monitor more than just personal information; they can monitor incoming and outgoing messages as well.
