Combo Cleaner vs ZoneAlarm

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.

ZoneAlarm is a long-standing name in personal cybersecurity, founded in 1997 and now operating under the umbrella of Check Point Software Technologies. Headquartered in San Francisco, they’ve built their reputation on firewall technology and have since expanded into complete antivirus and internet security solutions. Their services are geared toward individuals and small-scale users looking for a mix of automatic protection and manual control, particularly Windows users who want more say in what their systems allow and block. They offer a free antivirus plan with core malware defense and a personal firewall, and their paid plans add features like anti-ransomware, advanced phishing protection, and mobile security tools. Their standout features include a two-way firewall, real-time cloud-based scanning, and application-level controls, giving users a clearer window into their device’s behavior. Customer feedback is mixed. Some users praise the software’s reliability, ease of use, and long-term consistency, while others cite concerns around billing practices, support responsiveness, and occasional system slowdowns. ZoneAlarm has received recognition in the past, though they haven’t participated in recent third-party testing—something potential users may want to weigh. So what does all this mean for your device? Read on to explore whether their tools match your security needs.
