What is antivirus? How was it created? What is its working logic? What are the 5 best antivirus prog

Antivirus software is a program designed to protect computer systems from malicious software, including viruses, worms, trojans, malware, and other threats. These programs work by detecting and preventing the execution of malicious code on a computer. The creation of antivirus software dates back to the early days of computing when the first viruses began to emerge. Initially, antivirus programs relied on simple signature-based detection methods, where they would compare files on a computer to a database of known virus signatures. Over time, as malware became more sophisticated, antivirus software developers began incorporating additional detection techniques, such as heuristic analysis, behavior monitoring, and machine learning algorithms, to identify and block emerging threats. The basic operation of antivirus software involves several steps:
1. Scanning: The antivirus software scans files and system areas on a computer for known malware signatures or suspicious behavior.
2. Detection: If a potential threat is detected, the antivirus software takes action to quarantine, remove, or neutralize the threat. 3. Prevention: Antivirus software may also include real-time protection features that actively monitor system activity to prevent malware from executing.
4. Updates: Antivirus software relies on regular updates to its malware definition databases to stay effective against new and evolving threats. As for the top five antivirus programs, some popular options include:

1. Bitdefender Antivirus
2. Kaspersky Antivirus
3. Norton Antivirus
4. McAfee Antivirus
5. Avast Antivirus These programs vary in terms of features, performance, and user interface, so it's important to choose the one that best suits your needs and preferences.
