What Is Mysterium VPN's Malware Blocker?

Mysterium VPN's malware blocker is a built-in DNS filter. It checks every domain request against a list of known malicious and suspicious sites, and blocks the bad ones before they load. 

Because it works at the DNS level, it stops threats before a connection is even made. It's one part of the full set of Mysterium VPN features, and it's available on the Pro plan.

Is a VPN malware blocker the same as antivirus?
No. A DNS malware blocker stops connections to malicious domains before they load. Antivirus scans files, processes, and memory on your device for existing threats. They cover different threat vectors, so for full protection, use both.
