Combo Cleaner vs K7

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.

K7 Computing, founded in 1991 and based in Chennai, India, is a global cybersecurity company known for delivering fast, affordable, and resource-friendly antivirus protection. Their software is available across Windows, macOS, Android, and iOS, and is backed by a proprietary scan engine developed in-house. K7 offers essential and advanced features like real-time threat detection, Safe Surf web protection, parental controls, secure transactions, file backup and restore, junk file cleanup, and anti-theft tracking on mobile. Higher-tier plans also include webcam and microphone protection, a file shredder, a data locker, and device performance tools. Customers generally report a smooth experience, highlighting how K7 runs quietly in the background with minimal system impact. On platforms like Capterra and G2, it maintains strong ratings for ease of use, value for money, and overall effectiveness, although some users feel the interface and a few advanced features could use refinement.
