COMPUTER VIRUS DETECTION
Detecting viruses in a computer is crucial for maintaining system security and integrity. There are several techniques available to detect viruses, including:
Signature-Based Detection: This is the most common method where antivirus software scans files and programs for known virus signatures. These signatures are unique patterns associated with specific viruses. When a match is found, the software flags the file as malicious.
Heuristic Analysis: This method uses algorithms to detect suspicious behavior in programs and files that might indicate the presence of a virus. It can identify previously unknown viruses by analyzing code structures, file operations, and other behavioral patterns.
Behavioral Analysis: Also known as dynamic analysis, this technique observes the behavior of running programs in a controlled environment. It detects anomalies such as unexpected file modifications, network activity, or resource usage that might indicate a virus.
Sandboxing: This method involves running a program in a virtual environment (sandbox) to observe its behavior without affecting the host system. If the program exhibits malicious behavior, it can be identified and isolated.
File Integrity Monitoring: This technique involves monitoring important system files for unauthorized changes. If a virus attempts to alter these files, the system will detect and flag the change.
These techniques are often used in combination to improve detection rates and provide a comprehensive approach to identifying and neutralizing viruses on a computer system.
