Combo Cleaner vs F-Secure

Combo Cleaner is developed by RCS LT, a Lithuania-based company founded in 2007. What started as a local IT service provider has since shifted toward cross-platform cybersecurity tools, with their flagship product, Combo Cleaner, positioned as a mix of antivirus and system optimization. Available on macOS, Windows, Android, and iOS, their app aims to give users an all-in-one solution for essential threat protection and device maintenance. They offer real-time malware detection, disk cleanup, duplicate and large file scanners, privacy tools, and ransomware folder protection (on Windows). Their mobile apps focus more on photo cleanup, app management, and browsing safety. The platform is updated frequently, with hourly malware definition updates and an AI-powered security assistant to assist with scam detection and threat awareness. Users often note how easy their software is to install and navigate, though feedback around refund policies and the usefulness of the free version is mixed. While they’ve earned certifications like VB100 and OPSWAT Bronze, they haven't been evaluated by major independent antivirus labs. The simplicity of Combo Cleaner's tools appeals to many, but whether their performance matches their claims is a different matter. This review closely examines what they do—and what they leave out.

Founded in 1988 and headquartered in Helsinki, Finland, F-Secure has built a strong presence in the cybersecurity industry with a focus on privacy, simplicity, and reliable digital protection. Their antivirus products cater to individuals and families, offering cross-platform support for Windows, macOS, Android, and iOS. F-Secure Internet Security delivers core protection against malware, phishing, and ransomware, while F-Secure Total expands their offerings with a secure VPN, password manager, and identity breach monitoring—all under one streamlined interface. What sets F-Secure apart is their approach to transparency and data protection, with all services adhering to strict GDPR compliance. The software is praised for their ease of use and lightweight system impact, making it appealing to everyday users. However, user feedback is mixed, with some customers citing performance issues, feature limitations in lower-tier plans, and frustrations with customer support responsiveness. Backed by decades of industry experience and consistent performance in independent antivirus testing labs, F-Secure remains a compelling choice for users seeking straightforward, privacy-first security tools.
