Combo Cleaner vs PC Matic

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.

PC Matic is a U.S. cybersecurity company founded in 1999 and headquartered in Sioux City, Iowa. They began as a diagnostic software provider and have since evolved into an antivirus company offering protection across Windows, macOS, Android, and iOS devices. Their standout feature is application allowlisting, a prevention-based approach that blocks unknown programs by default, setting them apart from other providers. They offer several tiered plans that scale by features and device limits, with options like VPN access, cloud backup, and identity monitoring. While standard support is limited, users can add 24/7 access through a separate subscription.
They’ve earned solid marks from AV-TEST for protection and performance, but aren’t broadly evaluated by other major testing labs. Customer feedback varies, with some users appreciating their simple setup and lightweight design, while others report issues with false positives or difficulty accessing support without add-ons. This review explores their strengths, limitations, and overall value to help you determine whether their model fits your needs. Whether you’re interested in a more proactive defense or just weighing your antivirus options, read on to see where they stand.
