Malware is a type of malicious software designed to inflict harm on computers, networks, or users. It encompasses various forms, including viruses, worms, Trojans, ransomware, spyware, adware, and rootkits. Malware can steal sensitive data, disrupt operations, or provide unauthorized access to attackers.
Infection vectors for malware include email attachments, malicious websites, software downloads, and exploiting security vulnerabilities. Once installed, malware can perform a range of malicious activities, such as data theft, system damage, or spreading to other devices.
Preventing malware infections involves implementing robust security measures, including antivirus software, firewalls, and intrusion detection systems. Regular software updates and patch management are crucial to addressing vulnerabilities. Educating users about safe online practices and monitoring for suspicious activity enhances protection.
Effective malware defense requires a multi-layered security approach, combining endpoint protection, network security measures, and regular backups to ensure data recovery in case of an attack.
