What is Antivirus 

Antivirus software, also known as anti-malware software, is a type of software that is designed to detect and remove malware from computer systems and mobile devices. Malware is a broad term that refers to any software that is specifically designed to harm or exploit computer systems, and it includes viruses, worms, Trojan horses, ransomware, and other types of malicious software.

Antivirus software typically includes a combination of signature-based detection, which looks for known malware patterns, and behavior-based detection, which monitors the behavior of software and flags any suspicious activity. Some antivirus programs also include additional features such as firewalls, spam filters, and web protection to help protect against online threats.

Antivirus software is an important tool for protecting against malware and maintaining the security of a computer or device. It is important to keep the antivirus software up to date to ensure that it can detect and remove the latest threats. However, it is important to note that no antivirus program can provide 100% protection, and it is still important to practice safe browsing habits and be cautious when installing new software or opening email attachments.
