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 1992 and now part of OpenText, Total Defense is a U.S.-based cybersecurity company offering antivirus and internet security products. Their services span from basic protection for Windows and macOS to comprehensive suites that cover up to ten devices, complete with ransomware monitoring, phishing filters, cloud backups (10GB–25GB), and parental controls for safe browsing across the household. They offer an Android mobile app that adds real-time scanning, app lock, anti-theft tools, and privacy alerts without draining your phone’s performance. Each plan includes a 30-day free trial, U.S.-based support, and a 60-day money-back guarantee, giving new users room to explore. While they aren’t as prominent in third-party antivirus testing labs, Total Defense maintains high ratings across user review sites and holds an A+ from the BBB. With a clean interface, quiet performance, and reliable protection, they’re a worthy contender for anyone looking to secure their devices without diving into complex configurations or bloated extras.
