In addition to signature-based detection, antivirus programs also utilize behavioral analysis to identify suspicious files. This technique involves monitoring the behavior of files and applications on a computer. If a file exhibits unusual or malicious behavior, it is flagged as a potential threat and placed into quarantine for further analysis.
Heuristic scanning is another method used in the quarantining process. This approach involves comparing the characteristics of a file with a set of predefined rules. If a file meets certain criteria that indicate it could be malicious, it is quarantined for further investigation.
Identifying Potential Threats
Summary: Here, we will explore the various indicators that antivirus software uses to identify potential threats, such as behavioral analysis, signature-based detection, and heuristic scanning.
Antivirus software employs multiple indicators to identify potential threats and determine which files should be quarantined. One of the primary indicators is behavioral analysis, which involves monitoring the actions and interactions of files and applications on a computer. If a file exhibits suspicious behavior, such as attempting to modify system files or accessing sensitive information, it is flagged as a potential threat and quarantined for further analysis.
Signature-based detection is another commonly used indicator. Antivirus programs maintain a database of known malware signatures, which are unique patterns or characteristics of malicious files. When a file matches one of these signatures, it is identified as a threat and placed into quarantine.
Heuristic scanning is an indicator that focuses on the characteristics of a file rather than relying solely on predefined signatures. Antivirus software utilizes a set of rules or algorithms to analyze the file’s structure, behavior, and other attributes. If the file meets certain criteria that indicate it could be malicious, it is quarantined for further investigation.
