The type of software designed to detect and remove viruses from a computer is known as antivirus software. This software monitors and scans systems for malicious software, protecting against a range of threats, including viruses, worms, and spyware. Antivirus programs employ signature-based detection, behavior-based detection, and heuristic analysis to identify and neutralize threats proactively. Keeping antivirus software updated is essential for effective protection as new vulnerabilities and threats constantly emerge. Popular antivirus solutions include Norton, McAfee, and Bitdefender, which play a crucial role in cybersecurity.
