Cyber antivirus software is designed to identify malware, remove it, and prevent it from happening. This includes viruses, worms spyware, malware and other malicious programs that could cause harm to computers. Cybercriminals use this threat to steal data, disrupt system and destroy devices. Viruses are the most common type of cyber threat, however hackers can also develop Trojan attacks and worms. These threats can be used to steal personal information, damage systems and even control smart appliances, such as fridges that have life-saving drugs.
The most effective computer antivirus runs in the background, quietly protecting devices from infections. It should utilize a minimal amount of system resources and provide quick scanning speeds, along with an intuitive user interface that doesn’t get in the way of your daily tasks. It’s crucial to choose an antivirus that is compatible with your operating systems and doesn’t take up excessive CPU or memory.
Early antivirus software relied upon signatures – digital fingerprints to recognize malicious programs. This method is often behind the times, as hackers constantly alter their malware’s code to stay out of detection. The latest antivirus software uses different methods to detect threats. These include analyzing the structure, behavior and other aspects of a program. This technology is called Heuristics analysis.
Cyber-security software is becoming more important as the threat landscape becomes complex. Cyberattacks can affect any device connected to the internet including cars and smart fridges. A recent study revealed that computers that are not secured are targeted every 39 seconds.
