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 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.
Every day the Doctor Web anti-virus laboratory receives several hundred thousand program samples. Every day tens of thousands of entries are added into the company’s virus databases. These are the threats with which virus analysts are already familiar and for which neutralisation routines have been designed. However, programs that have not yet been analysed by information security experts are the ones that benefit cybercriminals the most.
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 analysed 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.
Dr.Web KATANA starts protecting a system during the boot-up phase, even before the traditional, signature-based anti-virus is loaded!
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 neutralises the actions of active malware programs without overloading the system.
Dr.Web KATANA’s protection is based on non-signature-based search methods, the neutralization of malware, and cloud protection technologies. The product analyses and monitors all system processes and blocks those that exhibit malicious behaviour.
Traditional behavioural analysers are based on predefined rules describing the behaviour of legitimate programs. Such rules are well known to criminals. Dr.Web KATANA acts differently. This product analyses the behaviour of each running program in real time by comparing it with the reputation information stored in the Dr.Web cloud which is constantly being updated. Dr.Web KATANA subsequently uses that information to determine whether a program is dangerous and then takes whatever measures are necessary to neutralise the threat.
Traditional behavioural analysers monitor the requests malicious programs make of various system resources. But what if a malicious program, having infiltrated the browser, makes no requests of the system and simply modifies, for example, the screen you use to interact with your bank?
Dr.Web KATANA monitors malware activity within processes so that attempts to steal confidential information or transfer money from your account will be prevented in a timely manner!
You won't have to purchase Dr.Web KATANA—its protection technologies have been incorporated into the Dr.Web applications you are using.
Developers try to release patches quickly for known vulnerabilities. For example, Microsoft releases security updates quite often. However, users often install some of them way too late (or don't install them at all). This encourages intruders to search for new vulnerabilities and exploit those that have been discovered but aren't yet closed on the computers that are being targeted.
Today, one of the most popular ways for malicious programs to penetrate a system is via the installation of add-on applications in the guise of useful software.
Increasing the protection level provides the system with additional security in the event malware that has not yet been added to the Dr.Web virus database is active. But, at the same time, the risk increases for conflicts to arise between the prohibitions that have been placed on the system by the preventive protection and the requirements of the running applications.
Unlike a traditional anti-virus, Dr.Web KATANA does not contain a signature database, a component that requires updating.
The anti-virus protection algorithms in Dr.Web KATANA are implemented as executables and libraries. Periodically, updates are released to improve these algorithms and fix detected errors.
To detect malicious actions, Dr.Web KATANA uses information stored by the anti-virus locally as well as Dr.Web Cloud reputation data which includes:
Dr.Web KATANA’s cloud system can collect information about Dr.Web’s operation on PCs, including data about brand-new threats, which enables Doctor Web to respond promptly to discovered defects and update rules stored on a computer locally.
