Cyber antivirus software is designed to identify malware, remove it, and prevent it from happening. This includes viruses, worms spyware, as well as other malicious programs that can cause harm to 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 which contain life-saving medications.
The best computer anti-virus works in the background, quietly securing devices from infection. It should make use of minimal system resources and provide quick scanning speeds, as well as an easy-to-use interface that does not hinder the flow of daily tasks. It’s also important to look for an antivirus that’s compatible with your operating system and doesn’t use up a significant amount of memory or power.
Early antivirus software relied upon signatures – digital fingerprints to recognize malicious programs. But this method is often playing catch-up since attackers constantly change the code of their malware to evade detection. The latest antivirus software uses several methods to identify threats, including analysing the structure of a program, behavior and other characteristics. This technology is known as the heuristic analysis.
Cyber-security software is becoming more important as the threat landscape becomes more complex. Cyberattacks can target any device connected to the internet including cars, smart fridges. A recent study has revealed that every 39 seconds, unprotected computers are targeted.
