Antivirus software protects against malware and viruses

Antivirus software protects computers from malware and viruses by scanning for harmful code and blocking attacks. It runs in the background, monitoring internet connections and comparing software against an updated database of known threats. In addition to real-time scanning, antivirus programs can quarantine suspicious files and periodically check for local infections. Advanced features include blocking harmful websites and offering a virtual private network (VPN) for secure online browsing. However, antivirus software is not foolproof. Some viruses may evade detection, as hackers continuously develop new methods. Machine learning and AI are being integrated to enhance detection and response to emerging threats.
