Combo Cleaner Review: Where Antivirus Meets System Cleanup

Combo Cleaner Overview

Combo Cleaner is developed by RCS LT, a Lithuania-based cybersecurity company founded in 2007. They began as a local business offering computer repair and security solutions, and over time transitioned into a dedicated developer of macOS and Windows applications. Today, they are best known for Combo Cleaner — an all-in-one antivirus and system optimization suite designed primarily for individual users. Their tools are available globally across macOS, Windows, iOS, and Android platforms, and they also maintain PCrisk, a cybersecurity news and education portal aimed at helping the public stay informed about emerging online threats.

Combo Cleaner’s approach combines malware protection with performance tools in a single package. Their software includes real-time antivirus scanning, ransomware protection, disk cleanup, and privacy features, all backed by a research team that provides hourly malware definition updates.

In terms of credibility, Combo Cleaner is VB100 certified, meaning they have passed independent testing for the software's ability to detect known malware without false positives. In 2017, they were also awarded Bronze certification from OPSWAT, reflecting compliance with recognized standards in security application development.

Features & Services

Shared features

These tools appear on more than one version of Combo Cleaner (desktop and/or mobile) and provide core value across the product line:

• Real-time protection: This feature, found on macOS, Windows, and Android, monitors downloads, app installations, and file activity in real time to block threats before they can cause harm
• Web browsing protection: This feature is available on Windows, Android, and iOS, and it prevents users from accessing known phishing or scam websites during their browsing sessions
• Big files finder: This tool, included in macOS and Windows versions, helps users identify and remove large files that take up unnecessary disk space
• Duplicate file finder: Found on macOS and Windows, this scans for redundant junk files like repeated documents or media, freeing up storage and improving file organization
• Photo cleaner: Available on Android and iOS, this feature detects duplicate, poor-quality, or outdated photos to help users manage their media libraries

macOS features

• Antivirus protection: Combo Cleaner continuously monitors your Mac in the background, scanning files as they are downloaded, opened, or modified. This real-time layer is designed to intercept adware, spyware, and malware infections before they can take root or cause damage
• Adware detection: While the software focuses on macOS threats, it also detects Windows-based malware. This ensures you don’t unknowingly distribute infected files to colleagues or friends using other operating systems
• Disk cleaner: Over time, temporary files, caches, and leftover application data can occupy valuable disk space. The disk cleaner does a quick scan of your system for these non-essential files and offers a safe, efficient way to remove them
• Smart scan utility: With a single command, Combo Cleaner can clean out various forms of clutter—downloads, app logs, trash, and more. It’s a streamlined way to maintain system hygiene without manual effort
• External drive scanning: This function extends Combo Cleaner’s cleaning capabilities to connected external hard drives, making managing backup drives or media archives easier
• Privacy scanner: Combo Cleaner audits your browsers for stored data like cookies, history, and cache files. Removing this information enhances privacy and reduces the risk of accessing personal data through the browser
• Browser performance boost: Clearing stored web data doesn’t just protect privacy, it also improves responsiveness. Combo Cleaner supports Safari, Chrome, Firefox, and Opera, offering system-wide browser maintenance
• App uninstaller: Uninstalling apps on macOS doesn’t always remove related support files. Combo Cleaner detects and deletes these residual files, providing a more thorough removal process

Windows features

• Real-time threat detection: As new files are downloaded or applications are launched, Combo Cleaner inspects them in real time. This proactive defense helps neutralize threats before they can affect your system
• Ransomware folder protection: To safeguard critical data, users can designate specific folders, such as documents or personal archives, for active monitoring. These folders are shielded from unauthorized changes or encryption attempts

Android features

• Malware scanner: With a simple scan, users can check for malicious or suspicious apps already present on their device. This straightforward method ensures that everything currently installed is secure
• Cleaner utility: Android devices often accumulate hidden cache files, temporary data, and unused remnants from old apps. This utility clears out digital clutter, improving available space and device performance
• App uninstaller: The software displays a comprehensive list of installed apps, including usage frequency and size, to help you decide which ones to remove, especially those rarely opened or draining resources
• Photo cleaner: Duplicate or poor-quality photos can clutter your gallery. This feature reviews your media library and highlights images that may be safely deleted, making cleanup more efficient
• App manager: To optimize device performance, Combo Cleaner identifies apps that use excessive battery, bandwidth, or send constant notifications. You can close or restrict them directly from the interface

iOS features

• Password checker: This tool allows you to verify the strength and security of your passwords and check whether any of them have been involved in known data breaches, helping you take timely action
• Identity protection: This tool allows you to check whether your email address has been compromised in a breach and view details about the incident. It’s a proactive step in digital safety
• SMS and calendar protection: Combo Cleaner scans incoming text messages and calendar invites for malicious links, helping users avoid scams disguised as everyday communications
• VPN: Combo Cleaner’s built-in VPN offers encrypted browsing and IP masking, handy on public Wi-Fi or when accessing content restricted by region. Users can switch between global server locations while maintaining privacy and internet security on their iPhone

What Are Their Plans & Pricing Options?

Combo Cleaner isn’t sold as a traditional standalone antivirus. Instead, it’s an all-in-one utility and security suite. Users must purchase the complete software package to unlock antivirus features like real-time protection, ransomware defense, and the AI security assistant.

The free version gives you access to cleaning tools like a disk cleaner, duplicate file finder, and big files finder—and you can also run a quick anti-malware scan. Full antivirus protection requires a paid subscription, but a seven-day free trial is available if you request it after downloading the app.

• Essential: $47.95 for one device
• Premium: $79.95 for up to five devices (adds priority support)
• Advanced: $139.95 for up to ten devices (adds one-on-one issue resolution)

All plans are billed every six months and unlock all desktop features, though availability varies by platform used.

The mobile app is free to download on iOS and Android. On iOS, features like web protection, Secure Calendar, and SMS Security require a subscription. Meanwhile, on Android, features like anti-malware engine and app manager, including real-time protection and web browsing safeguards, require a subscription.

• $4.99 for one month
• $7.99 for three months
• $14.99 for twelve months

The Combo Privacy VPN is sold separately and includes AES-256 encryption, a no-logs policy, and access to 3,000+ global servers. It's available on Windows, macOS, and Android. The one-month plan costs $17.95 and is billed monthly, the six-month plan is priced at $59.95, billed semi-annually, and the annual plan is billed at $69.95.

Advantages

AI-powered assistance

Their artificial intelligence chatbot, Personal Security Assistant, can review messages, emails, or screenshots to help you determine whether something looks suspicious. It’s a hands-on way to learn about threats and get quick feedback on potential scams.

Hourly malware definition updates

Combo Cleaner update their malware definitions every hour, which helps the software respond to emerging threats as they spread and reduces users’ window of vulnerability.

Integrated security and performance tools

Instead of splitting functionality across separate products, Combo Cleaner bundles antivirus protection with performance optimization tools into one application. This reduces clutter, simplifies updates, and gives users a clearer view of their device’s health.

Disadvantages

No third-party antivirus test results

Independent testing organizations like AV-Test or AV-Comparatives haven’t evaluated Combo Cleaner. This lack of transparency makes it difficult to objectively compare their protection performance against better-known antivirus providers.

Limited customer support channels

The only way to get help is by submitting a ticket — there’s no phone line, live chat, or direct email support. While responses may be adequate for basic questions, users dealing with urgent issues or technical bugs may find the process slow or impersonal.

Pricing is relatively high

Combo Cleaner’s base pricing starts at $47.95 for just six months of coverage on a single device, which is already more expensive than many mainstream antivirus providers offering full-year plans. However, the cost rises significantly if you also want to use their Combo Privacy VPN, which is sold separately. With the VPN priced at up to $17.95 per month or $69.95 per year, users who want security and privacy features could pay far more than they would with an all-in-one competitor.

Limited free version

Combo Cleaner’s free desktop version only offers cleanup tools — antivirus scanning and real-time protection are locked behind a paid plan. Users expecting a basic level of malware detection in the free version may be disappointed.

Feature inconsistency across platforms

Combo Cleaner’s feature set differs depending on the device. For example, macOS includes tools like privacy scanning and app uninstallation, while Windows users get ransomware folder protection, a feature unavailable on OS. While each version is tailored to its platform, the uneven distribution of key features, especially security tools, may impact the user experience for those expecting uniform functionality across devices.

The Customer Experience

Combo Cleaner has a few customer reviews across major platforms, but the existing feedback offers a consistent look at user sentiment. On Trustpilot, the company holds a respectable 4.1 out of 5, based on a mix of detailed reviews about the desktop software.

Their mobile app on the Google Play Store carries the same 4.1 out of 5 rating from 51 reviews. The App Store reflects a 3 out of 5 score, although this is based on a single rating with no written commentary.

Positive reviews

Many users commend Combo Cleaner as an accessible and multifunctional tool that combines antivirus protection with cleanup utilities like a disk cleaner and duplicate file finder. Users appreciated its ability to detect threats early and maintain system performance without slowing down their devices. Several reviewers mentioned switching from more well-known antivirus tools after experiencing system lag on laptops and desktops, and were pleasantly surprised by Combo Cleaner’s speed and efficiency.

The software’s ease of use is frequently noted as a strength, especially among those with limited technical experience. A few reviews also praised the responsiveness and professionalism of the support team, particularly when resolving licensing or installation issues.

Mobile users also gave positive feedback on the app’s clean interface and overall usability. Several appreciated the convenience of optimization tools and found the app effective for quick system maintenance tasks. While some acknowledged that the app doesn’t cover every advanced function, they found it helpful for basic performance cleanup and general protection on the go.

Negative reviews

Despite the positive remarks, Combo Cleaner has also received criticism across several key areas. A common concern among reviewers was the software’s detection reliability. Some users felt the app flagged issues that didn’t exist or failed to catch certain malware, especially browser hijackers, raising doubts about its scan accuracy. Others expressed frustration with the free version, which some felt was primarily geared toward upselling the paid plan without delivering meaningful results.

Refund requests were another recurring issue, with several users claiming that their refund was delayed, denied, or not processed at all, despite being requested within the advertised guarantee window. A few users also reported being charged again after canceling, leading to further dissatisfaction.

On the mobile side, criticism focused on technical limitations and stability issues. Some users said the app’s cleaning features didn’t go deep enough or failed to scan key areas like hidden files or RAM. There were also reports of bugs, including unexpected screen rotation, feature crashes, and incomplete photo cleaning. Others felt the free version was too restricted, offering little value without upgrading to the premium version.

Customer Support & Service

Combo Cleaner offers support primarily through an online ticketing system, rather than traditional channels like phone or direct email. Users who want to contact the company for general inquiries can fill out a basic contact form on their website, which requires a name, email address, and message.

For product-related issues, troubleshooting, or help using the software, Combo Cleaner directs users to a separate support page where they can submit a more detailed support ticket. In addition to their website, they maintain a Facebook account, where users can follow updates and announcements or ask informal questions.

Conclusion

Combo Cleaner takes a utility-first approach to antivirus by blending basic security features with system cleanup tools. They aim to simplify device maintenance by packaging malware protection, disk cleaning, and privacy tools into one app. This can be a practical fit for users who prefer convenience over complexity.

Their strengths vary by platform—macOS users get browser cleanup and app uninstall tools, while Windows users benefit from ransomware folder protection. However, they don’t offer third-party antivirus test results, and most core features are locked behind a paid plan. Their pricing may also feel steep compared to other providers that bundle security and privacy tools at a lower cost.
