Shield your computer from threats that your anti-virus cannot yet recognize.

Dr.Web KATANA Review at a Glance

Currently, the number of infections on home and corporate PCs is growing. This is large because criminals have learned to design malware that can’t be detected by its signatures. Furthermore, in addition to Windows PCs, poorly protected network hardware and mobile devices are now the targets of cyber-attacks too. As many as 20 entries for new Trojan.Encoder variations are added into the Dr.Web virus database on a daily basis! Cyber-criminals use a streamlined malware development cycle that includes testing their malware against all popular anti-viruses.

A non-signature anti-virus offering preventive protection against the latest active threats, targeted attacks, and attempts by Trojans and exploits to use vulnerabilities, including zero-day ones, to penetrate systems. Dr.Web KATANA by Doctor Web consists of a set of next-generation Dr.Web anti-virus technologies that is designed to provide advanced protection. It will shield your computer from threats that your anti-virus cannot yet recognize.

Dr.Web KATANA offers protection against the latest malicious programs that have been designed to bypass detection by traditional signature-based scanning and heuristic mechanisms. These programs have not yet been analyzed by the anti-virus laboratory and, therefore, are unknown to Dr.Web at the moment of intrusion. They include the latest encryption ransomware programs, Trojan injectors, and Trojan blockers, as well as threats that use zero-day vulnerabilities.

The functionality of anti-virus software must constantly be enhanced to keep pace with ever-evolving and ever-increasing numbers of malware programs. An antivirus must be able to operate without interruption in anticipation of an imminent attack. Such enhancements often decrease computer performance and irritate users to the point that they sometimes prefer to disable their anti-virus protection in order to allow their computers to work faster. Dr.Web KATANA’s developers have significantly enhanced computer security to create a new product that is practically invisible in terms of system load and system resources. Dr.Web KATANA neutralizes the actions of active malware programs without overloading the system.
