Antivirus (AV) software is a computer program or set of programs that seek, detect, prevent and/or remove software viruses and malware (like worms, trojans and adware). Initially developed to protect against computer viruses, AV’s scope has expanded to address the proliferation of new types of malware, including ransomware, keyloggers, phishing, social engineering, spyware, malicious URLs, spam, advanced persistent threats (APT) and DDoS attacks.
