Security software refers to programs designed to protect computers and networks from threats such as viruses, malware, and unauthorized access. Common types of security software include antivirus programs, firewalls, and anti-malware tools. These applications work by scanning for harmful content, blocking suspicious activities, and providing real-time protection against potential threats. In addition to protecting individual devices, security software can also help secure networks and cloud services. Many businesses use comprehensive security solutions to safeguard sensitive data and ensure compliance with regulations. Regular updates and scans are essential for maintaining the effectiveness of security software against evolving cyber threats.
