Dr.Web Katana is a new security tool from the Russian Antivirus firm ‘Doctor Web’, the developer terms it as an next-gen security tool for advanced protection.This security tool protects your PC against new threats that a traditional antivirus tool doesn’t recognize, because Dr.Web Katana doesn’t rely on signature-based virus and uses proactive technologies.
Dr.Web KATNA protects your system against computer threats by means of non-signature-based technologies — using behavior analysis, cloud-based threat detection, and preset rules. The program does not conflict with third-party anti-viruses and can operate in a team with them to enhance your computer’s security. Moreover, the application is simple and uses your systems very lightly.
Dr.Web KATNA utilizes mainly three technologies namely : Dr.Web Process Heuristic, Dr.Web ShellGuard and Dr.Web Cloud. The behavioural analysis technology Dr.Web Process Heuristic protects systems against new, highly prolific malicious programs that are capable of avoiding detection by traditional signature-based analysis and heuristic routines.
Dr.Web Process Heuristic analyses the behaviour of each running program in real time by comparing it with Dr.Web Cloud which is constantly updated. It determines whether the program is dangerous and then takes whatever measures are necessary to neutralize the threat. This data protection technology helps minimize losses resulting from the actions of unknown malware — and consumes very few of the protected system’s resources.
Dr.Web ShellGuard technology protects system from programs that exploit vulnerabilities. Exploits are malicious objects that take advantage of software flaws. The vulnerabilities are used to gain control over a targeted application or the operating system.
Installation of this security tool is simple and straight forward, by default the app just sits on windows taskbar and starts protecting your PC. If you want more control, click the ‘spider’ 
icon in the notification area (task bar jump list) and then click ‘settings’
, from here enable or disable protection, change the protection level (Optimal, medium, paranoid), configure exploit prevention and set the update frequency.
Overall, Dr.Web Katana can be used as a top-up for your existing security suite , but not as a replacement. This non-signature anti-virus offers 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.
