Cyber antivirus software is designed to identify, prevent and remove malware. This includes viruses and worms as well as spyware and other malware that could harm computers. Cybercriminals use these threats to steal data, hijack systems, and destroy devices. Hackers are also able to create Trojans and worms. These threats can be used to steal personal data or damage systems, and can even manage smart appliances such as refrigerators that contain life-saving medication.

This technique is known as Heuristics analysis.

As the threat landscape becomes increasingly complex, the need for effective cyber antivirus software becomes more urgent. Any device that connects to the internet is at risk of being targeted by box virtual data room cyberattacks from cars to smart fridges that can be controlled from anywhere in the world. A recent study revealed that computers without security are targeted every 39 seconds.
