Symptoms that look like viruses but almost never are

Before installing cleaning software, it's worth eliminating the most common problems. Most "infected" cell phones that come in for repair actually have one of these issues—and none of them can be solved with a scan.

• Battery draining quickly. A battery is a consumable component and loses capacity over time. After two or three years of daily use, shorter battery life is expected behavior, not a sign of tampering.
• The device is slow and keeps freezing. Almost full storage will severely impact the performance of any cell phone, because the system needs free space to function. Check how much space you have left before blaming viruses.
• Advertisement within an app. This free app displays ads — that's how it gets paid for itself. Annoyance is not synonymous with malicious.
• Website notification requesting attention. At some point you tapped "allow notifications" on a website. It then started notifying you of things, sometimes appearing as system alerts. Revoking permission in your browser settings puts an end to the problem.
• Heating up during heavy use. Gaming, video recording, leaving the camera on for extended periods, and fast charging are designed to cause the device to heat up.
• High data consumption. Automatic video quality, photo backup, and app updates via mobile network explain almost all cases. The settings show usage per app.
• The app opened by itself. Many open in the background through legitimate scheduling, and the system may reopen what was open before restarting.

What really deserves attention is another set of issues: icons you didn't install, apps that don't appear in the list but send notifications, full-screen ads outside of any app, constant browser redirection to strange pages, charges for services you didn't subscribe to, and messages sent in your name. That's when a complete cleanup is worthwhile.

Step-by-step guide to cleaning a suspicious Android device.

Order matters. Many malicious programs protect themselves against uninstallation, which is precisely why many people try to remove them and fail.

1. Disconnect from the internet. Airplane mode stops all data transmission while you are working.
2. Restart in safe mode. On most devices, press and hold the power button, then tap and hold the "Power off" option until the safe mode offer appears. In this mode, the applications you installed are disabled—preventing the malicious program from reacting while you remove it.
3. Revoke accessibility permission. In Settings, look for Accessibility and turn off anything you don't recognize. This is the permission that allows the screen to be read and simulated touches.
4. Remove the administrator from the device. In Settings, under Security, there's a list of administrator apps. As long as the app is listed there, the uninstall button is blocked. Uncheck it first.
5. Uninstall what shouldn't be there. Go to the full list of applications, sort by installation date, and look for what appeared around the time the problem started.
6. Close the front door. While still on the safe side, check which apps are authorized to install other apps and disable any that don't need it.
7. Clear your browser. In your browser settings, disable website notifications, clear your browsing data, and check that your homepage and default search engine remain your own.
8. Restart normally and run a scan. With the device back in normal mode, let Play Protect and your security app perform a full scan.
9. Update the system. Many attacks exploit vulnerabilities that have already been patched. The pending update is often part of the problem.

The false alert that screams that you are infected.

There's an entire category of scam that doesn't actually infect anything: it just convinces you that you've already been infected. It's the page that appears out of nowhere, with a countdown, an alert sound, and a message claiming that the device has several viruses, that the battery is damaged, or that your network operator has detected an intrusion.

How to recognize it in three seconds: No website can scan your phone.. A page opened in a browser doesn't have access to installed applications or battery status; it only knows the approximate model of the device, which is enough to seem convincing. If the "diagnosis" came from a page, it's always advertising or a scam.

What to do: Don't touch any buttons on the page, not even the "cancel" button — close the entire tab. If the screen freezes, close the browser through the recent apps manager. Then, clear your browsing data and revoke notifications from that website. And, most importantly, don't install the program the page offers or download any installation files from outside the official store: that's how the problem, which was imaginary, becomes real.

The same applies to calls and messages that urgently claim your account has been hacked and ask you to install a security app. No company fixes security by requesting installations over the phone.

After cleaning: what to replace and in what order

Removing the malicious app is only half the job. If it's been reading your screen for a few weeks, what it's taken from you remains valid outside. The order below is not random: it starts with the key that opens all other doors.

1. Change the password for your main email account on a different device. Whoever controls the email resets the password for almost everything. Doing this from a still-suspicious cell phone is pointless.
2. Enable two-step verification. In email, messaging apps, and the bank. It's the measure with the best return of all.
3. Close the open sessions. Email accounts, social networks, and messaging apps have a list of connected devices. Delete anything you don't recognize.
4. Check the email forwarding and rules. A common trick is to create a rule that sends a copy of your messages to another address. This survives password changes.
5. Review the bank's app. Reduce transfer limits, check authorized devices, and review your transaction history from the last few days. If you notice any unusual activity, report it through official channels immediately.
6. Change any duplicate passwords. If the same password was used for multiple services, they all need to change — and become different from each other.
7. Let the people you live with know. Hacked accounts are often used to solicit money from contacts. A short warning in the family group chat prevents further harm.

When cleaning doesn't solve the problem, as is the case with the iPhone.

If, after all this, the strange behavior continues—full-screen ads, apps that restart on their own, persistent redirects—a factory reset is the way to go. Two precautions make all the difference: save photos and documents manually, without Restore a full backup of your apps, because restoring will bring the problem back; and after reinstalling, install one app at a time, only from the official store, so as not to repeat the source.

On the iPhone, the scenario is different because one app can't interfere with another. When someone says their iPhone "got a virus," it's almost always one of three things: a website notification accidentally authorized, which can be resolved in the browser settings; an unwanted calendar invitation, created by a calendar subscription that needs to be deleted from the calendar list; or a configuration profile installed from a link, which appears in the profile management area of the settings and must be removed. None of the three requires antivirus software—it just requires knowing where to turn it off.

Questions that come up during cleaning

I can't uninstall the app. The button is grayed out.

This happens when the app is registered as an administrator on the device. Go to security settings, remove it from that list, and the uninstall button will work again. It's easier in safe mode.

Do I need to pay someone to clean my phone?

In most cases, no. Safe mode, revoking permissions, and uninstallation resolve the issue without cost. Be especially wary of services that advertise or contact you by phone offering paid removal.

Does resetting to factory settings remove the virus?

Delete whatever you installed, which is the source of the problem in virtually all real-world cases. The common mistake is then restoring a full backup that contained the problematic application.

Was my SIM card cloned or was my phone hacked?

These are different things. Suddenly losing signal and seeing your account being accessed from another location suggests a SIM card change, which is a problem with the carrier and needs to be reported to them. Strange ads and behavior on the device point to an installed application.

Is it worth installing two cleaning programs just to be sure?

No. Besides conflict and consumerism, many "cleaners" are precisely the type of app that fills your device with advertisements. A well-known security app, combined with the system's native protections, covers all the necessary aspects.

How do I know if someone is viewing my screen?

Check the list of apps with accessibility permissions and the device administrator list, as well as the camera and microphone usage indicators that current systems show at the top of the screen. And remember: monitoring another adult's device without consent is a crime in Brazil.
