Clean Master Ultra Security is a different product than the older Clean Master cleaner most Android users remember. This one pitches itself as a security suite: it checks your email against a password-leak database, flags installed apps that request microphone or camera access, tests whether your current WiFi network is secure, and includes a screen dead-pixel check as a bonus. The features work. The friction is the widget it wants installed to run the real-time monitoring, the paid unlock it pushes for the deeper checks, and the fact that the branded name still carries the reputation baggage of the Cheetah Mobile cleaner era. If you want the same security jobs done by vendors with longer track records and cleaner install flows, these seven Clean Master Ultra Security alternatives cover it.

Why people leave Clean Master Ultra Security
The reviews split into three groups. The first are users who expected a phone cleaner and got a security app, which is the branding problem. If you land on Clean Master Ultra Security looking for the RAM booster the earlier Clean Master shipped, the security features feel unrelated to the name.
The second group hits the widget requirement. Real-time monitoring runs through a foreground-service widget that has to sit on the home screen. That is the developer’s workaround for Android’s aggressive background-service kill on modern versions, and it works, but a lot of users skip installing widgets and never turn the feature on.
The third and largest group is about trust. Independent AV benchmarks (AV-Test, AV-Comparatives) do not include Clean Master Ultra Security in their scored rounds, so there is no third-party confirmation of the detection engine. Compared to Bitdefender, Norton, Kaspersky, Avast, and Malwarebytes (all scored quarterly), this is a real gap for a paid security product.
The seven Clean Master Ultra Security alternatives below either come with third-party benchmark scores, ship a cleaner install flow, or focus narrowly on a single security job.
The alternatives
1. Bitdefender Mobile Security, the detection leader
Bitdefender Mobile Security consistently ranks at or near the top of AV-Test’s Android round, with detection scores at or above 99.9% on both prevalent and zero-day samples across the last several years of reporting. The engine is cloud-augmented, so on-device impact stays low; battery drain during a full scan is a fraction of what Norton and AVG measure. On the security side it includes Web Protection for Chrome and other browsers, an Account Privacy check (the same email-in-breach lookup Clean Master Ultra Security runs), Anomaly Detection for suspicious behavior, and an integrated app lock.
The trade-off is the 14-day free trial and the subscription that starts after. Bitdefender does not offer a permanently-free tier the way Avast and AVG do.
Pricing: 14-day trial, then subscription starting around $14.99 per year for one device.
Migration from Clean Master Ultra Security: no data transfers. Install Bitdefender, uninstall Clean Master, done.
Bottom line: pick Bitdefender if detection accuracy is the priority and you accept a paid subscription for it.
2. Norton 360, the bundle pick
Norton 360 rolls antivirus, a no-log VPN, a password manager, Dark Web Monitoring, and a Wi-Fi Security scanner into one subscription. On the Android build, all of those features live inside one app, and the interface is the most polished of any suite on this list. Norton’s detection scores sit alongside Bitdefender’s and Kaspersky’s at the top of the AV-Test rankings, and the VPN allowance is generous compared to the free tiers Avast and AVG offer.
The trade-off is price. Norton’s introductory year is discounted, and the renewal is where the sticker shock lands. Users on the Play Store frequently mention letting the subscription lapse after year one.
Pricing: 30-day trial, then Norton 360 Standard from about $29.99 for the introductory year.
Migration from Clean Master Ultra Security: none needed.
Bottom line: pick Norton 360 if you want AV, VPN, and password manager under one bill and are okay with the renewal price.
3. Kaspersky Standard, the technical pick
Kaspersky Standard ships one of the most technically respected mobile AV engines and pairs it with a limited VPN allowance and a password strength check. The Android app’s scan is fast, the WiFi scanner names the specific issue (weak protocol, open network) rather than a red-yellow-green rating, and the app-permission audit surfaces the same category-level warnings Clean Master Ultra Security does, with fewer nags.
The trade-off is trust context outside Russia. Kaspersky is banned from U.S. federal networks and several allied government uses; consumer builds remain widely available and independently audited, but the geopolitical noise is real and worth naming. The company runs a Global Transparency Initiative with third-party source code review in Zurich and other cities.
Pricing: limited free tier for basic scanning. Standard starts around $19.99 per year.
Migration from Clean Master Ultra Security: none needed.
Bottom line: pick Kaspersky if you value the engine on technical grounds and the geopolitical context is not a blocker.
4. Avast One, the generous free tier
Avast One is the free-tier pick, and by a wide margin. The free build ships the antivirus scan, a Wi-Fi Inspector, a Password Leak check, and a small allowance of the built-in VPN (about 5GB per week). The interface consolidates all of that under one home screen, and the recent redesign hides most of the upsell nags behind a single Premium tab rather than sprinkling them across features.
The trade-off is the same as it has been since the 2015 acquisition of AVG: Avast Software makes money on the paid tier and on aggregate market data. The 2020 Jumpshot subsidiary shutdown addressed the browsing-data reselling issue, but the ad model in the free tier is a reminder that free is not zero-cost.
Pricing: free with a Premium upsell starting around $4.99 per month.
Migration from Clean Master Ultra Security: none needed.
Bottom line: pick Avast One if you want the biggest free security package and are comfortable with the free-tier ad model.
5. AVG AntiVirus, the familiar interface
AVG AntiVirus & Security is Avast’s sister brand and shares the same detection engine. The reason to pick AVG over Avast comes down to interface preference: the AVG UI is more compact, the on-boarding shorter, and the free-tier features focus on a Photo Vault and App Locker on top of the standard scan. If you liked the older AVG Free desktop app, the mobile build carries the same aesthetic.
Feature parity with Avast means the trade-offs are also the same. Ad model in the free tier, upsells to the Pro tier for anti-theft and camera trap features.
Pricing: free with Pro starting around $4.99 per month.
Migration from Clean Master Ultra Security: none needed.
Bottom line: pick AVG if you prefer its interface to Avast’s and want a Photo Vault as part of the free tier.
6. Malwarebytes, the adware specialist
Malwarebytes takes a narrower brief than the full-suite picks above and does it well. The mobile scanner is optimized for detecting adware SDKs, potentially unwanted programs, and browser-hijacking apps: the exact class of nuisance that a “Clean Master” brand history is most associated with. If your motivation for Clean Master Ultra Security was cleaning up a device that already looked compromised, Malwarebytes is the second-opinion tool that catches what the primary suite might have missed.
The trade-off is scope. Malwarebytes’ mobile app does not ship a VPN, a password manager, or a WiFi scanner. It scans, it flags, it cleans, and stops there.
Pricing: free on-demand scan. Premium (real-time protection + Web Protection) from about $3.33 per month billed annually.
Migration from Clean Master Ultra Security: none needed.
Bottom line: pick Malwarebytes as a second scanner or when adware and unwanted SDKs are the specific concern.
7. Bouncer, the permission scalpel
Bouncer approaches the “dangerous permissions” job from a different angle. Instead of listing apps with camera or microphone access and asking you what to do about it, Bouncer lets you grant a permission for a single session (camera for the QR-scanner app, microphone for the voice memo) and automatically revokes it once you exit the app. It is a small, tightly focused utility rather than a full suite, and it fills the exact gap Clean Master Ultra Security’s “dangerous apps” screen tries to close.
The trade-off is scope. Bouncer does not scan for malware, does not check password leaks, and does not test WiFi. It runs the permission scalpel and nothing else.
Pricing: one-time purchase of about $3.99. No subscription.
Migration from Clean Master Ultra Security: none needed. Install, grant the accessibility permission Bouncer needs to revoke on your behalf, and select the apps whose permissions should auto-revoke.
Bottom line: pick Bouncer as a companion to any of the suites above when granular permission control is what you actually want.
How to choose
Pick Bitdefender Mobile Security if you want the highest independently-benchmarked detection rate and are willing to pay for a single-purpose security app.
Pick Norton 360 if you want to consolidate AV, VPN, and a password manager under one subscription and are comfortable with the renewal price. It is the closest to a Clean Master Ultra Security replacement in scope.
Pick Avast One if free matters more than premium features. The free tier is the most generous of any name-brand security app and covers the same jobs Clean Master Ultra Security’s paid unlock does.
Pick Malwarebytes or Bouncer as second-opinion or scalpel tools alongside a primary. Both do one thing well and neither tries to be a suite.
Stay on Clean Master Ultra Security if the widget-based real-time monitoring works for your home-screen layout, and the specific bundle of email leak, WiFi check, and dangerous-apps audit fits your routine. The features work; the alternatives above just come with independent benchmark backing and a longer trust history.
FAQ
Is Clean Master Ultra Security safe to install?
The app’s listed features work as described and the Play Store listing is signed and current. The trust question is external validation: independent AV benchmarks like AV-Test do not rank Clean Master Ultra Security, so there is no third-party confirmation of the detection or leak-check engines. For paid security software, that gap matters.
What is the best free Clean Master Ultra Security alternative?
Avast One. The free tier includes an antivirus scan, WiFi Inspector, Password Leak check, and a modest VPN allowance. AVG AntiVirus is the same underlying engine with a different UI and a Photo Vault added.
Can I check if my email has been in a data breach without an app?
Yes. Have I Been Pwned (haveibeenpwned.com) does the same lookup Clean Master Ultra Security runs, in a browser, for free. It supports domain-level monitoring for teams and integrates with password managers like Bitwarden and 1Password.
Do I need a security app if I only install from Google Play?
Google Play Protect scans Play Store installs and blocks known-malicious sideloads. That covers the majority of cases. A dedicated security app adds detection for sideloaded APKs, browser-hijack scripts, and permission changes made by apps that were clean at install time. If you sideload from Aptoide, F-Droid, or APK sites, a second scanner is worth having.
What is the difference between Clean Master Ultra Security and the older Clean Master cleaner?
Different developer, different feature set, similar name. The original Clean Master (Cheetah Mobile) was a RAM booster and junk cleaner that was pulled from the Play Store in 2020 after ad-fraud investigations. Clean Master Ultra Security is a security suite from a different vendor that reuses the Clean Master brand. Features are password leak, WiFi scan, and dangerous-permission audit, with no cleaner-style RAM boost.
