It detects, quarantines, and removes malicious software from devices to safeguard user data and maintain system integrity. Regular updates to the antivirus database enable the software to recognize new threats. By providing real-time protection and periodic scans, antivirus solutions are essential for minimizing security risks associated with cyberattacks and ensuring the smooth functioning of a computer’s operating environment.
