Avast Mobile Security in 2026: Avast One Migration Guide

Avast Mobile Security 6.34.3 is not a current Android security choice. The old page at this address was published in December 2020, promoted that version as “Premium,” used one outdated promotional image, and sent readers to a third-party APK over an unencrypted HTTP connection. A filename containing “GooglePlay” did not prove that Google Play delivered the file, that Avast signed it, or that it included a valid paid subscription.

That APK link, the download call to action, the 540×900 image, and the unsupported “best protection” claim have been removed. This page is now an independent 2026 guide to the official transition from Avast Mobile Security to Avast One, safe installation, subscription migration, Android permissions, phishing and scam protection, privacy disclosures, independent lab results, Google Play Protect, lost-device protection, and complete removal. It does not host APK, XAPK, MOD, cracked, “Premium unlocked,” activation-code, or alternative-store files.

Replace an obsolete APK path with an official store installation, deliberate permissions, privacy review, and layered Android security

What Changed From Avast Mobile Security to Avast One?

Avast’s current support FAQ says the new Avast One app is replacing both Avast Mobile Security and the previous Avast One app on Android. Older listings are being removed from Google Play, and new installations receive the new Avast One experience. Avast Mobile Security users are updated automatically through Google Play, while users of the previous Avast One may be prompted to install the replacement and restore their plan.

The transition is gradual. A store page, icon, screen layout, or plan name can look different by region or rollout stage. The reliable checks are the official Google Play destination, developer identity, package, subscription account, and Avast’s current support notice—not an old tutorial screenshot.

Choose the Correct Migration Path

If the official Play page says Update, use it. If it says Install even though an Avast-looking app exists, stop and inspect the installed app under Android Settings. A repackaged app can copy a name and icon. Do not weaken Android’s Restricted settings protections to make an unknown sideloaded copy gain Accessibility.

Protect Data and Subscription Records First

Security apps can contain local data and configuration that do not survive removal. Photo Vault is the most obvious example: protected pictures may be encrypted or hidden inside app-managed storage. A subscription is separate from that local storage and may belong to Google Play, an Avast Account, or another authorized sales channel.

• Open Photo Vault in the trusted installed app and export every required image to a protected location you can verify independently.
• Open several exported files outside Avast; do not treat a visible filename as a tested backup.
• Record which Google Account purchased the subscription without recording its password.
• Record the exact plan, device count, renewal or expiry date, and order receipt.
• Check whether a VPN profile, App Lock PIN, monitored email address, or scam-protection feature needs reconfiguration.
• Capture necessary settings without exposing email, phone, billing, device, or recovery information publicly.
• On a managed phone, ask the administrator whether data belongs to a work profile and whether export is permitted.

Do not upload private vault images, receipts, account screens, email addresses, or device identifiers to a public support post. If the installed APK is already suspicious, do not open sensitive files inside it; obtain help and protect accounts from a separate trusted device.

Install Avast One Only Through the Official Store

On the Android device, open Google Play and verify all of these points before tapping Install:

• The current name is Avast One: Antivirus, Security.
• The developer is Avast Software.
• The web listing uses package com.avast.android.mobilesecurity.
• The listing clearly states that it contains ads and in-app purchases.
• The Data safety panel is available for review.
• The price, trial, billing period, renewal behavior, and included features shown to you are acceptable.

Open the official Avast One listing on Google Play

Keep automatic Play updates enabled unless a managed-device policy controls releases. After installation, start with the free path if it meets your need, run the initial review, and enable extra modules one at a time. This makes each permission request understandable and easier to reverse.

Why the Old APK Route Is Unsafe

An APK is an Android application package, not proof of malware and not proof of safety. Organizations can distribute legitimate private apps outside a public store, but a consumer download needs a trustworthy publisher, protected transport, signing identity, update channel, current version, privacy disclosure, and support owner. The removed page established none of those controls.

Do not solve an installation problem by disabling Play Protect, permitting unknown sources globally, accepting an unexpected certificate, or granting Accessibility to a mirror build. If the official app is unavailable for your device or region, use Android’s built-in protections and contact official Avast Support rather than substituting an archived APK.

Free, Basic, Premium, and Ultimate Are Not APK Editions

At the review date, Avast’s new-app FAQ described three paid tiers—Basic, Premium, and Ultimate—in addition to a free experience. It said Basic can include automatic scans, breach alerts, expanded Photo Vault, App Lock, and direct support; Premium adds scam-protection modules such as email, SMS, call, and link guards; Ultimate adds VPN access and can cover related Avast apps. The exact menu and offer can differ by region, platform, regulation, eligibility, and rollout.

Read the checkout screen, not an old review, as the price source. Confirm whether a trial automatically renews, the billing frequency, tax, device count, refund terms, and the account that will own the purchase. A VPN is an encrypted connection service; it does not make a malicious app trustworthy, repair an unsupported phone, or make every website legitimate.

Understand Every Permission Before Granting It

Android permissions are part of the product’s security boundary. Avast’s installation guide says setup can request background operation or a battery-optimization exemption, display over other apps, and Accessibility for real-time detections. Other modules can request file, location, contacts/account, SMS, phone, notification, usage, email, or VPN access. Requests can differ by Android version and selected feature.

Android lets you review a single app under Settings > Apps > Avast One > Permissions and review all apps by permission type under the Permission manager. Menu names vary by manufacturer. Revoking access can disable the related feature; that is expected and preferable to granting unused power permanently.

Accessibility and Restricted Settings Need Extra Care

Google explains that an Accessibility service can read content on the screen and interact with apps on a user’s behalf. That power supports legitimate assistive technology and security tools, but scammers also abuse it to capture information, approve actions, hide warnings, or resist removal. Newer Android versions can restrict this setting for sideloaded apps.

Use this decision rule:

1. Confirm the app came directly from Google Play and the developer is Avast Software.
2. Open the Avast feature that explains why Accessibility is needed.
3. Decide whether you want that feature enough to grant the access.
4. Enable only the named Avast service—not an unknown companion service.
5. Test the warning behavior, then review Accessibility again after app updates.
6. Disable the service before uninstalling or when you stop using the feature.

Review Current Data Safety and Product Privacy Notices

The Google Play Data safety label is developer-provided and may vary by use, region, and age. At the review date, the Avast One listing said the app may share app activity, app information and performance, and device or other identifiers with third parties. It said the app may collect location, personal information, and seven other data categories; data is encrypted in transit; and users can request deletion.

The more detailed Avast Product Privacy Notice connects processing to features. It describes files and detections used for malware scanning, URLs and referrers used for web protection, email addresses used for breach monitoring, and service or device events used for operation and improvement. It says breach monitoring works with SpyCloud. For Email Guard, the notice says suspected malicious email can be retained in raw form for analysis for 30 days unless the user opts out, with identifiers later removed for longer-term detection use; human review may occur when needed to investigate detection accuracy.

These disclosures do not automatically decide whether the app is right for you. They make the trade-off review possible:

• Enable only modules whose benefit you understand.
• Review Avast’s Personal Privacy or consent settings after installation.
• Do not connect an inbox, phone history, or vault merely because setup recommends it.
• Recheck the notice when a major version introduces new scam or AI features.
• Use Android’s Privacy dashboard to inspect recent permission access.
• Use the documented deletion request route if you stop using the service and want eligible account data removed.

Avast’s Historical Privacy Case Is Relevant Context

In June 2024, the United States Federal Trade Commission finalized an order resolving allegations about historical Avast and Jumpshot practices. The FTC said Avast and subsidiaries collected browsing information through antivirus products and browser extensions and sold information through Jumpshot without adequate notice and consent. The final order prohibited selling, disclosing, or licensing browsing data for advertising purposes, required deletion of Jumpshot data and derived products, required a comprehensive privacy program, and required a $16.5 million payment for consumer redress.

Avast’s settlement FAQ says it voluntarily closed Jumpshot and stopped that data operation in January 2020, disagrees with the FTC’s allegations and characterization, says the incident was not a data breach, and says it does not currently sell consumer data. Both the regulator’s final order and the company’s response are linked below.

This history should not be hidden, and it should not be distorted. It does not prove that the current Avast One Android app is malware. It does justify reading current disclosures carefully, minimizing optional data access, checking consent settings, and deciding whether the protection benefit matches your privacy expectations.

What Independent 2026 Tests Found

AV-TEST evaluated Avast Antivirus & Security 26.6 on Android 15 in May 2026. The product detected 100% of 3,039 recent real-time malware samples and 100% of 2,665 widespread samples in that test. It produced zero false warnings across the listed legitimate-app sets and received 6/6 for protection, performance, and usability.

AV-Comparatives’ 2026 Mobile Security Review tested Avast One Free 26.6. It reported a 99.6% protection rate, two false positives, and an Approved result. The review identifies Avast One Free as ad-supported and says Avast commissioned the free-tier test and review.

The numbers differ because timing, samples, configuration, network access, classification, and methodology differ. Neither result guarantees detection of a new exploit, targeted stalkerware, account takeover, fraudulent conversation, unsafe permission choice, or a future app version. Use lab evidence as one input alongside support, privacy, usability, device compatibility, and your threat model.

What Avast One Can and Cannot Protect

A current security app can scan accessible apps and files, check selected links and websites, flag risky settings, inspect supported Wi-Fi characteristics, alert about known leaked credentials, and add scam-review tools. It may help a user who receives many unfamiliar links, wants a second malware engine, or values guided security checks.

Avast’s own FAQ says no solution is 100% effective and an Android application cannot protect against every exploit targeting the operating-system kernel, network stack, or other fundamental components. It also cannot:

• Install missing Android, firmware, browser, or modem security patches.
• Make an unsupported phone safe for indefinite financial or administrative use.
• Prove that a caller, SMS sender, marketplace seller, investment offer, or support agent is genuine.
• Recover a Google Account after an attacker changes recovery details without using Google’s process.
• Protect data already disclosed to a scammer or entered into a phishing page.
• Replace a strong screen lock, encrypted backup, multi-factor authentication, or account alerts.
• Guarantee removal of an app installed as a privileged system component or protected by powerful admin access.
• Make arbitrary sideloading safe.

Security software is a layer, not an exemption from updates and judgment.

Keep Google Play Protect Enabled

Google Play Protect is built into supported Android devices and is on by default. Google says it checks apps before Play download, scans installed apps periodically, checks apps from other sources, warns about potentially harmful behavior, and can disable or remove harmful apps. It can also warn about privacy policy violations or unverified apps requesting permissions commonly abused for financial fraud.

To review it, open Google Play > profile icon > Play Protect > Settings. Keep Scan apps with Play Protect enabled. Also verify the device is Play Protect certified under Play Store settings. A certification problem is separate from the malware-scanning switch.

Do not disable Play Protect because another antivirus is installed. The services use different data, timing, and Android integration. If they disagree, pause before deleting a critical app: capture the exact detection, update both products, verify the publisher and source, and use official support. A false positive is possible; so is a newly detected threat.

Use Scam Protection as Advice, Not Authority

Avast One advertises Web Guard and Avast Assistant, with additional email, SMS, call, and link guards in eligible paid tiers. These features can surface risky URLs, message patterns, or known caller information. They are most useful as a prompt to stop and verify through another channel.

• Do not open a delivery, tax, prize, bank, job, romance, investment, or account-recovery link from an unsolicited message.
• Open the organization’s app or type its known address yourself.
• Call a number printed on the card, statement, or official site—not the incoming message.
• Never disclose a password, one-time code, recovery code, card PIN, or screen-sharing access.
• Treat urgency, secrecy, remote-access requests, gift cards, cryptocurrency, and “safe account” transfers as danger signals.
• A “safe” label is not proof; a “suspicious” label is not a legal judgment.

If an AI assistant analyzes submitted text, screenshots, links, or messages, remove unnecessary personal details and read the product notice first. Do not submit medical, legal, workplace, financial, or intimate content merely to obtain a quick verdict.

Configure Find Hub and Android Theft Protection

The archived image on the old page said Avast could locate and control a phone. Do not infer a current feature from that artwork. The current Avast One store and support material reviewed for this guide do not present phone location as the primary lost-device path. Android provides Find Hub and Theft Protection for that purpose.

Before loss or theft:

• Use a strong PIN or password and working biometric unlock.
• Verify Settings > Google > All services > Personal & device safety > Find Hub and allow the device to be located.
• Review offline-finding participation and its privacy options.
• Enable Theft Detection Lock, Offline Device Lock, Remote Lock, and Identity Check where the phone supports them.
• Keep a verified phone number and Google recovery methods current.
• Back up important data before a theft occurs.

Find Hub can locate, secure, mark lost, or erase an eligible device. Remote erase is destructive and may end further location. In a theft, do not travel alone to confront someone at a displayed location; involve the carrier and local authorities as appropriate.

If an Unknown Avast APK Is Already Installed

1. Do not sign in or buy anything inside it. Do not enter an Avast password, Google password, payment details, or recovery code.
2. Record the facts privately. Note the displayed package, install source, version, special access, date installed, and suspicious behavior.
3. Protect accounts from another clean device. If sensitive credentials were entered, change them and review sessions, recovery methods, passkeys, multi-factor authentication, and financial alerts.
4. Disconnect if active compromise is suspected. Use Airplane mode while preserving the ability to obtain authorized help.
5. Review special access. Check Accessibility, Device admin apps, VPN, notification access, display over other apps, install unknown apps, usage access, and battery exceptions.
6. Disable the suspicious app’s powerful access. Device-admin or Accessibility privileges can interfere with removal.
7. Uninstall it from Android Settings. Do not use an uninstaller supplied by the same download site.
8. Restart and run Google Play Protect. Update Android, Google Play system components, Chrome, WebView, and all apps.
9. Install the official app only if wanted. Return through the verified Google Play listing and configure from zero.
10. Escalate persistent signs. Unknown admin services, pop-ups outside apps, inaccessible settings, unexpected certificates, financial activity, or reinstallation can justify professional incident response or a carefully prepared factory reset.

A factory reset is not the first answer to every old app, but it can be appropriate when device trust cannot be restored. Back up personal documents and photos—not the suspicious APK or its configuration—and verify account access before erasing.

Uninstall Avast One Without Losing Data or Billing Control

1. Export and verify Photo Vault items and any other app-managed data.
2. Record the subscription owner, plan, renewal date, and receipt.
3. Turn off Avast App Lock or other overlays that could block Settings.
4. Disable Avast under Device admin apps if it was granted that role.
5. Disable the Avast Accessibility service and remove an Avast VPN profile if no longer needed.
6. Uninstall from Google Play or Settings > Apps > Avast One > Uninstall.
7. Restart and confirm that no Avast VPN, Accessibility, admin, or notification service remains.
8. If you do not want renewal, open Google Play with the purchasing account, choose Payments & subscriptions > Subscriptions, select the plan, and cancel it.
9. Keep the cancellation confirmation and verify the access end date.
10. Review Avast’s privacy controls and deletion-request process separately if you want eligible account data removed.

Do You Need Avast One?

A practical evaluation lasts longer than one scan. Watch battery use, notifications, false alarms, web compatibility, app conflicts, data consumption, consent settings, support quality, and whether you actually use the paid features. Do not buy merely to remove anxiety created by an upsell screen.

Build a Strong Android Security Baseline

1. Use a Play Protect-certified device still receiving Android, Google Play system, browser, and manufacturer security updates.
2. Keep Google Play Protect and automatic app updates enabled.
3. Install apps from Google Play or a documented organization store; remove “install unknown apps” access when finished with an authorized task.
4. Use a strong screen lock, short auto-lock time, SIM protection where appropriate, and biometric convenience backed by the PIN.
5. Secure the Google Account with a unique password, passkey or strong multi-factor method, recovery information, and sign-in alerts.
6. Configure Find Hub, Theft Protection, backups, and recovery before loss.
7. Review Permission manager, Privacy dashboard, Accessibility, Device admin apps, VPN, certificates, and notification access periodically.
8. Verify payment, delivery, bank, government, and support messages through a separately obtained official channel.
9. Keep at least one recoverable copy of important photos, documents, contacts, and authenticator recovery material.
10. If adding Avast One, install it officially, enable only selected modules, keep Play Protect on, and review renewal and privacy settings.

What Not to Do

• Do not download Avast Mobile Security 6.34.3 from a mirror, forum, file host, chat, or old backup.
• Do not search for Avast Premium unlocked, MOD, crack, license key, activation code, or patched billing.
• Do not disable Play Protect or Android Restricted settings to satisfy a sideloaded app.
• Do not assume an icon, package filename, screenshot, high rating, or “GooglePlay” label proves origin.
• Do not grant Accessibility, Device admin, SMS, phone, email, all-files, overlay, or VPN access without a selected feature and privacy review.
• Do not delete Photo Vault or app-managed data before a verified export.
• Do not pay twice before restoring the original Google Play or Avast subscription.
• Do not assume a security app can patch unsupported Android, guarantee scam detection, or make sideloading safe.
• Do not use an antivirus warning alone to accuse a legitimate publisher; verify evidence and seek official support.
• Do not uninstall and assume billing stopped.
