How does antivirus software protect a computer ... - SS1 ICT Computer Application Software Question

Antivirus software protects a computer by scanning files, programs, and data for known patterns of malicious code (viruses, malware, etc.). It identifies and removes or quarantines such threats to prevent them from causing harm. Examples of antivirus software include Norton Antivirus, McAfee, and Avast. These programs use a combination of signature-based detection (recognizing known threats) and heuristic analysis (detecting suspicious behavior) to safeguard against various types of malicious software.
