Hello there! How do antivirus software work? Well, antivirus software is designed to detect, prevent, and remove malicious software such as viruses, trojans, and worms from your computer or device. It uses various techniques such as signature-based detection, behavior-based detection, and heuristics to scan files and monitor the system for suspicious activity. When a threat is detected, the antivirus software may either remove or quarantine it, or give you options on how to deal with it. Regularly updating the antivirus software is crucial to keep up with the evolving threats and to ensure maximum protection.
