A malware (for malicious software) designates any type of harmful software, including viruses, worms, trojan horses, ransomware, spyware, adware, etc.

NextDNS can not replace an anti-virus but can prevent propagation of malwares by blocking the domains they use to proliferate. All NextDNS blocklists are gathered from well known public sources, refreshed hourly and available on our Github.
