Smartphones contain valuable personal information, including photographs, messages, banking applications, emails, and saved account details. If a malicious application or suspicious download puts that information at risk, your phone may begin displaying unwanted advertisements, redirecting you to unfamiliar websites, or behaving unusually.
Fortunately, several security tools can help identify potentially harmful applications, detect malware, and protect your device against online threats. Choosing a reputable tool and understanding how to use it can make phone security easier to manage.
However, no application can guarantee that it will detect or remove every possible threat. Most phone infections are caused by different forms of malicious software rather than traditional self-replicating computer viruses.
In this guide, we explore five security options, explain how to scan an Android phone, and share practical steps to take if you suspect your device has been compromised.
1. Google Play Protect: Start With Android’s Built-In Security
Google Play Protect is built into Google Play on supported Android devices. It checks applications for potentially harmful behaviour, including apps downloaded from outside the Play Store, and can warn users when a threat is detected.
For many Android users, this is the most sensible place to begin because it is already available without installing another security application.
Main Features
- Scans applications for potentially harmful behaviour.
- Checks apps before installation and periodically examines installed apps.
- Warns users about detected security threats.
- May disable or remove harmful applications.
- Provides additional safeguards against certain suspicious apps and permissions.
How to Scan Your Phone
- Open the Google Play Store.
- Tap your profile picture.
- Select Play Protect.
- Tap Scan.
- Review the results and follow any security recommendations.
Keep Play Protect enabled and install Android security updates when they become available.
Google explains that Play Protect can warn you about harmful applications and, in some cases, disable or remove them automatically. You can read more in the official Google Play Protect guide.
Who should use it?
Every Android user should start here. Play Protect provides an important baseline of security, although additional protection may be useful for people who frequently install applications, browse unfamiliar websites, or encounter suspicious links.
2. Bitdefender Mobile Security: Protection Against Malware and Scams
Bitdefender Mobile Security is a dedicated security application for Android phones and tablets. It offers tools intended to detect malicious applications, protect against dangerous websites, and reduce exposure to online scams.
Main Features
Malware scanning: Scan applications for threats and review security alerts.

Anti-theft features: Eligible plans include tools for locating or remotely securing a lost device.
Some features require a paid subscription, and availability can depend on your device and region.
How to Use Bitdefender
Download the application from its official store listing, open it, and follow the setup instructions. Run the available security scan and review any warnings before taking action.
If a suspicious application is detected, follow the application’s recommended removal instructions. Avoid ignoring a warning simply because the application appears familiar.
Bitdefender can be worth considering if you want a dedicated security suite with malware scanning and web protection in one place.

Warning Signs That Your Phone May Be Infected
Unusual phone behaviour does not always mean malware is present, but certain changes deserve investigation.
Persistent unwanted advertisements: Pop-ups appearing outside normal apps or repeated browser redirects can indicate an unwanted application or unsafe website settings.
Unknown applications: Apps that you do not remember installing should be reviewed.
Unexpected permission requests: Be cautious when an application requests sensitive access that does not match its purpose.
Suspicious account activity: Unexpected login alerts or messages sent from your accounts may indicate that credentials have been compromised.
Unfamiliar charges or settings changes: Unexpected financial activity or changes you did not make require prompt attention.
Battery drain, overheating, and slow performance alone do not prove that a phone is infected. These symptoms can also result from older hardware, demanding applications, or software issues.
How to Remove Malware From an Android Phone
If you suspect a malicious application is installed, take these steps.
Step 1: Stop Interacting With Suspicious Content
Do not tap suspicious advertisements, download unknown files, or enter passwords into unexpected login pages.
If you believe an account or payment application is actively compromised, disconnect from suspicious networks and use a trusted device to secure important accounts.
Step 2: Review Recently Installed Applications
Open Settings → Apps and review applications you installed around the time the problem began.
If an unfamiliar app appears suspicious, investigate it before removing it. Avoid deleting system applications unless you know what they do.
Step 3: Run Google Play Protect
Open the Google Play Store, select Play Protect, and run a scan. Follow any warnings it provides.
Step 4: Use One Reputable Security Scanner
If the problem continues, consider scanning with one reputable security app such as Malwarebytes or Bitdefender. Avoid installing multiple cleaners and antivirus apps from unknown developers.
Step 5: Use Safe Mode if Necessary
If unwanted pop-ups continue and you cannot uninstall a suspicious app, Safe Mode may help. It temporarily disables most third-party apps, making it easier to identify an application responsible for the behaviour.
The exact method for entering Safe Mode varies by phone manufacturer.
Step 6: Secure Your Accounts
If you entered a password on a suspicious website or suspect credentials were stolen, change those passwords from a trusted device. Prioritize email, banking, and other important accounts, and enable two-step verification.
Step 7: Consider a Factory Reset Only as a Last Resort
If serious malware problems persist, a factory reset may be necessary. It erases local data, so back up important files carefully and avoid restoring suspicious applications or files afterward.

What About Viruses on an iPhone?
iPhones use a different security model from typical Android devices. Traditional antivirus applications generally cannot scan the entire iOS system in the same way a desktop antivirus program can.
If an iPhone displays a warning that an application contains malware and cannot be opened, Apple recommends deleting that application rather than bypassing the warning.
You should also keep iOS updated, avoid installing untrusted configuration profiles, and remove suspicious applications or browser notifications.
Apple explains this process in its official malware-warning guidance.
Frequently Asked Questions
Can one app remove every virus from my phone?
No. No security application can guarantee detection and removal of every threat. Detection depends on the device, software version, permissions, and the nature of the malware.
Which is the first app I should use to scan Android?
Start with Google Play Protect, which is built into Google Play on supported Android devices. If necessary, consider one reputable additional security scanner.
Are free antivirus apps enough?
Built-in protection and free scanning tools can provide useful security features. Paid plans may add web protection, scam detection, or other capabilities, so compare features rather than assuming that the most expensive app is always best.
Should I install several antivirus applications?
Usually, one well-chosen security app alongside the built-in protections is sufficient. Several overlapping security apps may create unnecessary notifications and resource usage.
Can an antivirus remove suspicious pop-up ads?
It may identify the application causing them, but not every pop-up is caused by malware. Check recently installed apps, browser notification permissions, and website settings as well.
Conclusion
Keeping your phone secure requires more than downloading an antivirus application. Google Play Protect offers a useful starting point for Android users, while Bitdefender, Malwarebytes, Avast, and Norton provide additional security options with different features and pricing.
If you suspect malware, review unfamiliar applications, run a reputable scan, keep your operating system updated, and secure any accounts that may have been exposed.
Remember that no app can guarantee the removal of every threat. Regular updates, cautious downloads, sensible permissions, and safe browsing habits remain essential parts of smartphone security.
