Dr.Web Katana

Advantages

• Neutralizes the latest threats, not yet known to your antivirus, designed to remain undetected by traditional signature and heuristic mechanisms.
• Provides security almost from the moment the operating system is launched - Dr.Web KATANA begins protecting even before the traditional signature antivirus has finished loading!
• Unlike traditional antivirus, Dr.Web KATANA consumes virtually no resources.
• Monitors all system processes, identifies malicious programs based on their characteristic behavior and blocks them. Analyzes the behavior of each running program "on the fly", checking with the constantly updated reputation cloud of Dr.Web, and based on up-to-date knowledge of how malicious programs behave, makes a conclusion about its danger, after which it takes the necessary measures to neutralize the threat.
• It does not require any configuration and starts working effectively immediately after installation.
• Protects even without PC access to the Internet.
• Does not conflict with antivirus programs from other manufacturers.
• It consumes virtually no resources - the product requires only 36 MB of RAM to operate.

Functional capabilities

• Protects critical areas of the system from modifications by malware.
• Detects and terminates malicious, suspicious or untrusted scripts and processes.
• Detects unwanted file changes by monitoring all processes in the system for actions typical of malware behavior (such as ransomware), preventing malicious objects from infiltrating other programs' processes.
• Detects and neutralizes the latest threats: ransomware, injectors, remotely controlled malware (spread to organize botnets and espionage), and virus packers.
• Protects against exploits - malicious objects that try to use vulnerabilities to penetrate the system, including those not yet known to anyone except virus writers (so-called "zero-day" vulnerabilities).
• Controls the work of not only the most popular browsers, but also any plugins to them; protects against browser blockers.
• Blocks the ability of malicious programs to change boot areas of the disk in order to prevent them from running (for example, Trojans) on the computer.
• Prevents Windows from disabling Safe Mode by blocking registry changes.
• Prevents malicious programs from adding new tasks needed by attackers to the operating system's logic. Blocks a number of parameters in the Windows registry, which prevents viruses, for example, from changing the normal display of the Desktop or hiding the presence of a Trojan in the system using a rootkit.
• Prevents malware from changing program launch rules.
• Prevents downloads of new or unknown drivers without the user's knowledge.
• Blocks the autostart of malicious programs, as well as certain applications, such as anti-viruses, preventing them from registering in the registry for subsequent launch.
• Blocks registry branches that are responsible for virtual device drivers, making it impossible to install a new virtual device.
• Blocks communications between spyware components and the server that controls them.
• Prevents malware from disrupting the normal operation of system services, such as interfering with the regular creation of file backups.
