1. Antivirus

2. ANTIVIRUS Antivirus software is designed to detect, prevent, and remove malicious software (malware) from computers and other devices. It plays a crucial role in protecting your data and ensuring the smooth operation of your systems. Viruses, worms, or trojan horses can be used by criminals or mischievous people called 'hackers'. They can steal information or damage system files. If no antivirus software is installed on the device, hackers will be able to access the information in the computer.

3. Antivirus software monitors your devices for known threats and eliminates or stops them from infecting your devices as quickly as possible. With reliable security software like Norton AntiVirus Plus, your personal data will be better protected from hackers, malware, viruses, and other online threats. What does antivirus software do? Antivirus software works by scanning your devices regularly to look for and block known viruses as well as new and emerging malware strains. If your device gets infected, antivirus software will help you remove it. To provide the best possible protection, these programs use several forms of detection.

4. Features Antivirus software protects computers in many different ways. Most antiviruses offer more than just "virus" protection. They protect computers from all different kinds of malware, like spyware, rootkits, phishing, and ransomware. Antiviruses are frequently interchangeably referred to as "anti-malware" programs. In an antivirus scan, the software will look through every file on a computer, and it will compare each computer file's genetic makeup with the genetic makeup of already-known viruses. If a file has the same genetic makeup as a known piece of malware, it will be flagged as a problem. This is known as signature-based detection, and it is only effective when a malware file has been previously identified and shared with the community of malware researchers who maintain the malware database. Another typical kind of malware detection is through behavior analysis. This is when the antivirus software identifies an abnormal behavior in a computer file or program, causing the antivirus to flag that issue and assess whether or not the abnormality has been caused by malware.

5. Types of Antivirus Software Signature detection Antivirus programs use  signature detection to look for specific pieces of code that are found in known viruses  in order to contain and remove them. Signature detection is a core component of most antivirus software, but it’s reactive – a virus must be known for its signature to be added to antivirus software. That means if signature detection gets used on its own, it won’t protect you from new and emerging viruses. Example : Norton Antivirus uses signature-based detection to identify and block known threats

6. Heuristic-Based Detection Description : This method analyzes the behavior of files and programs to detect new, unknown viruses. It looks for suspicious activities or code patterns. Example : Bitdefender Antivirus employs heuristic detection to identify potentially harmful software based on its behavior Behavior-Based Detection Description : This approach monitors the behavior of programs in real-time. If a program behaves suspiciously, it is flagged as a potential threat. Example : Malwarebytes uses behavior-based detection to monitor and block malicious activities

7. Machine Learning-Based Detection Description : This advanced method uses machine learning algorithms to identify malware. It can adapt and improve its detection capabilities over time. Example : Sophos Intercept X leverages machine learning to detect and prevent malware

8. Uses of Antivirus Software Protection Against Malware Description : Antivirus software protects against various types of malware, including viruses, worms, Trojans, ransomware, and spyware. Example : McAfee Total Protection offers comprehensive protection against a wide range of malware Real-Time Scanning Description : Antivirus programs continuously scan files and applications in real-time to detect and block threats as they occur. Example : Kaspersky Antivirus provides real-time scanning to ensure ongoing protection

9. System Performance Optimization Description : Some antivirus software includes tools to optimize system performance by removing unnecessary files and managing startup programs. Example : Avast Antivirus includes performance optimization features to keep your system running smoothly Web Protection Description : Antivirus software often includes web protection features to block malicious websites and phishing attempts. Example : Trend Micro Antivirus provides web protection to safeguard your online activities

10. Drawbacks of antivirus Antivirus software has its downsides, though you can mitigate most of these by investing in better programs. A few of these drawbacks include: Looking out for adware:  Free antivirus protection from unknown or untrustworthy brands may not be reliable and can even be a source of adware. While you may not want to spend money on antivirus protection, weigh the cost of that program against the price of a new device.

11. Slowing down devices and system updates:  If you’re running a lot of programs and then turn on your antivirus or run an in-depth scan, it could slow down your device. Some antivirus applications may deliberately stop your apps or programs from updating to make sure those updates don’t introduce vulnerabilities that the antivirus software may not be able to detect and protect against. Avoiding programs that are slow to detect new malware:  If you’re using unreliable free antivirus software, it may be using signature detection as the primary method for discovering malware. That means new viruses and malware can make their way onto your computer before your antivirus even knows. That’s why the best antivirus software uses a combination of signature and heuristic detection.

12. How to choose antivirus software? There are many factors to consider when choosing antivirus software for your device. One important factor is compatibility with your operating systems Performance impact is another important consideration. Some antivirus programs may slow down your device or consume many system resources, which can be frustrating. Therefore, choosing a program that balances solid protection and minimal impact on performance is crucial. Another factor to consider is the prevalence of false positives, which are instances where the antivirus software incorrectly identifies a benign file as a threat. This can be frustrating and may result in losing important files or data. Therefore, choosing a program with a low rate of false positives is vital. It is also essential to consider the reputation and privacy policy of the antivirus software company. Choose a company with a good reputation for protecting customer data and respecting privacy .

13. Cost is an important factor to consider as well. The more security features beyond anti-malware you want, the more expensive the product becomes. Only you can decide where the perfect compromise between price and protection lies. The following are the core features to consider : Firewall:   A  firewall is a security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall can be hardware-based, software-based, or a combination of both. Its primary purpose is to keep unauthorized users and malicious software out of a private network while allowing authorized users and legitimate traffic to pass through .

14. Password manager:  A  password manager  is a software tool that helps users securely store and manage their login credentials for various online accounts. It generates strong, unique passwords for each account and stores them in a secure, encrypted format. This helps users avoid using weak or reused passwords, which can easily be guessed or hacked. Virtual private network (VPN):  A  VPN  is a network technology that creates a secure, encrypted connection over a public network (such as the internet). It allows users to transmit data as if their devices were directly connected to a private network, even if they are physically located elsewhere. VPNs are often used to protect online privacy and anonymity, as well as bypass censorship and geo-restrictions

15. Parental controls :   Parental controls  allow parents or guardians to limit their children’s Internet usage and access to certain content. They can block inappropriate websites and apps, set time limits on device usage, and monitor online activity. Parental controls can help protect children from online dangers such as cyberbullying, predatory behavior, and exposure to inappropriate content Identity theft protection :   Identity theft  protection is a service that helps users monitor and protect their personal information from being used for fraudulent purposes. It typically includes credit monitoring, alert notifications, and recovery assistance. In addition, identity theft protection can help users detect and prevent unauthorized use of their personal information, such as credit card numbers or social security number

16. Secure cloud storage (cloud backup):   Cloud backup is a service that allows users to store copies of their data on a remote server (the “cloud“) to protect it from local disasters, hardware failures, or data loss. Cloud backup can be configured to automatically save new or changed files regularly, making it a convenient and reliable way to ensure data is always backed up and available for recovery. Anti-phishing :   Anti-phishing is a security feature that helps users identify and protect themselves against fraudulent websites or emails designed to steal sensitive information (such as login credentials or financial information). It can be implemented as a software tool that analyzes websites and emails for known phishing indicators, or as an education program that teaches users how to recognize and avoid phishing attacks

17. Anti-ransomware:   Anti-ransomware is a security feature that helps users protect their devices and data from ransomware attacks. Ransomware is a type of malicious code that encrypts a user’s files and demands payment (the “ransom”) in exchange for the decryption key. Anti-ransomware can detect and block ransomware attacks in real-time, or provide tools for recovering encrypted data.

22. Uses An antivirus software protect computer system from any unknown threats like viruses, spywares and other internet which can get into your computer through various means like external drives or through internet access. No matter whatever, system user’s surf online, they know their system will not get affected by virus threats. And most importantly if the users click by chance on an unwanted link/URL, antivirus will send an immediate message to the user. Hence, installing an antivirus into the system is the best way keep working hassle free thereafter. With raising awareness of the threats caused by scammers, it is always wise to use security software to avoid threats as users don’t actually know when they are going to get infected by unknown viruses, spyware and other internet threats.

23. Uses According to an FBI survey, major businesses lose $12 million annually dealing with virus incidents.  A survey by Symantec in 2009 found that a third of small to medium-sized business did not use antivirus protection at that time, whereas more than 80% of home users had some kind of antivirus installed. According to a sociological survey conducted by G Data Software in 2010 49% of women did not use any antivirus program at all. In the present IT world, we strongly recommend use of antivirus software or anti spyware to keep your system free from any unknown threats which could result in big financial loses and even can result in data loss which is the most dangerous case.
