These techniques include signature-based detection, where known virus signatures are compared to the files on your computer, and heuristic analysis, which detects suspicious behavior or code patterns. Some antivirus programs also employ real-time protection, monitoring your computer for any malicious activity as it occurs. When a threat is detected, the software takes appropriate action, such as quarantining or deleting the infected file.
