: AI algorithms are trained on massive datasets to distinguish between "good" and "malicious" code patterns, allowing for better detection of brand-new malware families. Responding to Threats

: Completely deleting the malicious file or application from the device. What Is Antivirus Software? - Sophos

: This method looks for suspicious code structures or characteristics shared with known malware. It helps identify new variants or "polymorphic" viruses that have altered their code to avoid signature detection. How Does Antivirus Software Work? – AZMATH

: This is the traditional method where the software compares file code patterns (signatures) against a database of known threats. It is highly effective for established malware but cannot detect "zero-day" threats that haven't been cataloged yet.

Antivirus software protects your computer by detecting, blocking, and removing malicious software (malware). Modern solutions employ a multi-layered detection pipeline to catch both known and emerging threats. Primary Detection Methods : AI algorithms are trained on massive datasets

: Instead of looking at what a file is , this analyzes what a file does . If a program attempts suspicious actions—like encrypting files (ransomware behavior) or disabling security tools—it is flagged, even if the software has never seen that specific code before. Advanced Protection Features

: Many products send data about unknown files to a cloud database for rapid analysis based on collective threat intelligence from millions of other users. - Sophos : This method looks for suspicious

When a threat is identified, the antivirus typically offers three responses:
