The latest antivirus software utilizes different methods to identify threats, including analysing the structure of a program, behavior and other characteristics. This technology is called Heuristics analysis.

Cyber-security software is increasingly important as the threat landscape becomes more complex. Cyberattacks can target any device connected to internet including cars, smart fridges. A recent study has revealed that every 39 seconds, unsecured computers are targeted.
