What is an Anti-Virus Scanner?
An anti-virus scanner is a software application designed to protect computer systems by identifying and removing malicious software, also known as malware, from the system. The primary function of an anti-virus scanner is to keep a system protected from infections and to provide security to critical data and information.
The applications and uses of computers have increased manifold, making it a crucial tool in everyday life. However, the same technology that makes it so beneficial can also make it vulnerable to cyber-attacks. Hence, it is crucial to protect your computer system from malware, viruses, and other malicious threats.
An anti-virus scanner provides protection from all forms of malware, such as viruses, worms, Trojans, adware, spyware, ransomware, and other malicious software. The scanner analyses files and applications to detect viruses and malware and initiates the process of quarantine or deletion if deemed necessary.
An anti-virus scanner protects against both known and unknown threats. It not only detects new malware but also has the ability to recognize and eliminate new variants. Often, an anti-virus scanner uses third-party analysis tools to stay up-to-date with the latest malware threats.
Anti-virus scanners work by using a combination of signature-based detection and behavioral-based detection. Signature-based detection checks files against a database of known malware signatures, whereas behavioral-based detection identifies suspicious behavior and alerts the user accordingly.
An anti-virus scanner is updated regularly to keep it up-to-date with the latest malware threats. The updates contain information on the new types of malware, including the signatures and behavior patterns of newly discovered malware.
In addition to detecting and removing malware, an anti-virus scanner also provides a range of other security features, such as web filtering and parental controls. Web filtering blocks malicious websites and phishing emails, while parental controls allow parents to monitor their children’s online activity.
To summarize, an anti-virus scanner is an essential tool to keep your computer protected from malware, viruses, and other malicious software. It provides an extra layer of security to your system and ensures the safety of your data and information. With continuous updates and enhancements, anti-virus scanners remain an effective and reliable tool for cyber-security.
