Dr.Web Katana is designed to protect against new threats that your anti-virus is not yet equipped to recognize. The new anti-virus Dr.Web Katana is based on proactive technologies that do not involve the use of virus databases: the decision as to whether a particular malware program should be neutralised is made only on the basis of a mining model of the behaviour of the applications running on a computer.

Modern encryption ransomware and operating system blockers are among those dangers that cannot always be thwarted by a signature-based anti-virus. The number of requests submitted to Doctor Web’s technical support service for help just with Trojans in the Trojan.Encoder malware family recently reached 60% of the total number of requests made, which indicates that this is a real epidemic. And the vast majority of requests are from users of other anti-viruses. The new product Dr.Web Katana eliminates these particular threats.

Another strong point of the new product Dr.Web Katana is that it offers protection against malware that exploits vulnerabilities in software that is installed on a computer. These programs, exploits, are currently in high demand on the market of cybercriminal "services".

Dr.Web Katana does not use virus databases (and, therefore, does not have a virus database that requires updating). The product is virtually invisible with regards to system load and resource consumption. Furthermore, it does not require any configuration.
