Combo Cleaner vs Defencebyte

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 2013 and headquartered in Toongabbie, New South Wales, Defencebyte is an Australian cybersecurity company offering antivirus software for Windows devices. Their antivirus solution includes real-time protection, behavior-based threat detection, automated scanning, and system rollback tools. The software is designed to run quietly in the background without slowing down performance, which is especially useful for users with legacy systems. Defencebyte offers multi-device coverage, flat-rate pricing, a 30-day free trial, and a 30-day money-back guarantee. While their products haven’t been reviewed by major independent testing labs and their online activity has slowed since 2022, users have praised the tool’s simplicity and ease of use. For those looking for minimal, real-time antivirus protection with low system impact, Defencebyte may still be worth considering.
