Definition of Antivirus:
Antivirus, short for anti-virus, is a type of software designed to detect, prevent, and remove malicious software (malware) from computer systems. Malware includes viruses, worms, trojan horses, spyware, adware, and other harmful programs that can compromise the security and functionality of a computer.
Types of Antivirus:
1. Signature-Based Antivirus:
Relies on a database of known malware signatures.
Compares files on the computer to these signatures to identify and eliminate threats.
2. Heuristic-Based Antivirus:
Uses behavior analysis to detect suspicious activities and identify potential threats based on their behavior.
Doesn't rely solely on known signatures but looks for patterns of behavior indicative of malware.
3. Behavioral-Based Antivirus:
Monitors the behavior of programs in real-time.
Identifies and blocks activities that are characteristic of malware, even if specific signatures are not known.
4. Cloud-Based Antivirus:
Leverages the power of cloud computing to analyze files and identify threats.
Allows for real-time updates and quick response to emerging threats.
Examples of Antivirus Software:
1. Norton Antivirus:
