Our verdict on Kaspersky Anti-Ransomware Tool
Kaspersky Anti-Ransomware Tool is a free standalone Windows application for desktops, laptops, and Windows servers. It monitors files and applications for ransomware and cryptomalware, automatically scans and monitors files, and blocks ransomware and crypto-malware activity. The tool also detects crypto-miners, adware, pornware, and riskware. It is suited to individuals and organizations seeking an additional ransomware-focused layer alongside existing security software, rather than a broad security suite or cross-platform product.
The main strength is its focused protection workflow. Cloud-assisted behavioral detection is designed to identify suspicious activity, while automatic scanning and monitoring help watch files and applications during normal use. Rollback can reverse unwanted file and registry changes, adding a recovery-oriented feature to the blocking and detection functions. Compatibility with most existing security software also makes the tool relevant where another security product is already installed. The published plans show separate home and business versions: Home covers up to five devices per account, while Business protects up to 50 devices and adds email reporting.
Platform coverage and support status define the main trade-offs. The product is limited to Windows, and its deployment is on premises, so it is not a fit for buyers seeking protection across multiple operating systems or a broader cloud-managed security platform. Kaspersky’s support documentation states that Anti-Ransomware Tool for Business 3.0 and previous versions are no longer supported, even though the current official product page presents free home and business downloads. Choose it for free Windows ransomware monitoring with behavioral detection and rollback; consider an alternative if supported business tooling, wider platform coverage, or a broader security scope is essential.
