Welcome to the Malware Patrol Project!

We are a small company of security experts based in São Paulo, Brazil. Our history is one of community spirit and dedication to internet security that began in 2005 when a group of like-minded individuals began sharing malicious links through a mailing list. Since these humble beginnings, our block lists have grown to cover millions of URLs and continue to provide threat protection to users in more than 175 countries.

We have developed an automated system that monitors URLs every day for the presence of viruses, Trojans, worms, or any other known type of malware. We also monitor the command and control (C&C) servers used by ransomware. Our team is continually updating the technology used to scour the web for threats and compile it into useful, actionable data.

Our services are available for the protection of both commercial and non-commercial users. For ease of use, our commercial data feeds are fully customizable and our non-commercial block lists are available in a variety of formats, compatible with the most popular network and email security systems.
