Our verdict on Dr.Web KATANA
Dr.Web KATANA is a paid, non-signature antivirus for Windows desktops, laptops, netbooks and tablets. It is aimed at Windows users who want preventive protection against active threats, targeted attacks, malicious scripts, encryption ransomware, exploits and previously unknown malware. The product monitors process behavior in real time, protects critical system areas and can work alongside third-party antivirus software. Its focused design suits buyers seeking a dedicated Windows protection layer rather than a broad security package.
According to the vendor's pricing page, the 1 PC / 1 year plan costs $9.30 per PC annually, while the 1 PC / 2 years plan costs $17.67 per PC annually. Both plans include non-signature antivirus and preventive protection for Windows. A 30-day free trial is also available. The core feature set includes cloud reputation-based analysis, malicious script and process blocking, protection during system boot-up, offline system protection, and exploit and zero-day vulnerability protection. This makes the product's value proposition straightforward: focused threat prevention at a low annual price for a single Windows PC.
Dr.Web KATANA fits best where Windows compatibility and ransomware defense are the main priorities. Its ability to run alongside third-party antivirus software may also suit users who want an additional preventive layer. The tradeoff is its narrow platform and antivirus focus: the listed plans are for one PC, and the product is not positioned as a complete multi-platform security suite. Choose it for targeted Windows protection and behavior-based detection; choose another option if you need broader device coverage or a wider set of security tools.
