Antivirus is software that looks for and removes malware from a computer, mobile phone, or network. It scans files, applications, and other content to identify and block cyber threats from entering a device. Antivirus can also help users understand and manage risk by detecting vulnerabilities and educating them on how to avoid phishing attacks.

Most antivirus software uses signature-based detection, which matches the digital fingerprints of known malware to its databases. But hackers regularly tamper with malware to create polymorphic strains that alter their code signatures, so AV programs must continuously update their databases to keep up. This can slow down devices and interrupt regular system updates, which may introduce weaknesses that attackers can exploit.

In addition to traditional signature-based detection, modern antivirus tools use heuristics and behavior analysis to look for patterns and characteristics commonly associated with viruses. This helps AV detect previously unknown malware. Once antivirus detects a threat, it isolates it from other files and programs, preventing it from running operations that could damage or infect other programs, then deletes it.

For most of us, antivirus is a crucial layer of defense against common cyberthreats that can threaten our devices, privacy, and data. But even with antivirus and other layered security solutions, we should all practice safe online habits to reduce our risks, such as avoiding suspicious links, using two-factor authentication for email accounts, encrypting sensitive information, backing up data regularly, and limiting device access to trusted networks.
