Quick answer
Do not tap the warning, call its number or install the cleaner it advertises. Identify which app sent the notification. For Chrome site alerts, review Chrome’s notification permissions and remove the unwanted site’s access. If ads appear outside the browser or the home screen changed after an installation, investigate recent apps and run the phone’s trusted protection checks. A webpage’s virus count is not a verified diagnosis.
Choose the check that matches your symptom
Start with the row that describes what you see. You do not need to try every step.
| What you notice | Where to start |
|---|---|
| Alerts identify Chrome or a website | Review website notification permission |
| Ads appear outside the browser or the home screen changed | Investigate recent apps |
| A password or payment detail was entered | Protect the affected account |
Before you start
- Use the exact model and platform described below. If a label or connection differs, stop and identify it before changing settings.
- Keep passwords, verification codes, serial numbers and private documents out of any help request. Use synthetic or redacted details when describing an error.
Why this happens
A site can send frightening notifications after receiving permission. An installed app can also display intrusive ads or change the launcher. Those causes need different checks: suppressing one browser alert will not remove a separate unwanted app, and buying antivirus is not required to revoke a website’s permission.
What to do, step by step
Try one step at a time. Stop when the issue is resolved. If an instruction doesn't match your device, use the official model-specific guidance instead.
Identify the source without opening the warning
- Leave the advertisement’s buttons, phone numbers and download prompts alone. Do not pay for a scan from the alert.
- Review the notification’s app name and, when displayed, website name. Note whether it appears only while browsing or also on the home screen.
- If the home screen changed after a recent app installation, record that timing and app name. Avoid treating an advertised number of viruses as a real scan result.
Review Chrome notification permissions
- Open Chrome yourself. Open More, then Settings, Site settings and Notifications.
- Review the sites allowed to notify you. For an unfamiliar or unwanted site, open its notification entry and block or remove its notification permission using the control shown.
- If you prefer no website notifications, turn the top notification setting off. This is different from Android’s ordinary messaging notifications.
View larger Check for an unwanted recently installed app
- If ads continue outside Chrome, open the phone’s Settings and Apps. Review apps installed around the time the problem began, using your own installation history.
- Uninstall a clearly identified unwanted third-party app using its normal Uninstall control. Keep a note of what was removed; do not remove system components at random.
- On a Samsung Galaxy that is difficult to use, its documented safe-mode startup uses Volume down during startup after the Samsung logo appears. Because button sequences vary, use the exact model’s safe-mode directions before attempting this.
Run trusted protection and update checks
- Open Google Play Store, select your profile and Play Protect. Review its protection status and enable Scan apps with Play Protect if it was disabled.
- On a Samsung model that displays Battery and Device Care and Device protection, use Scan phone there. Menu names vary with One UI and region.
- Install offered system and app updates through the phone’s own Settings and trusted stores. Do not install a cleaner from an advertisement or an unknown download.
View larger Check the result and protect any exposed accounts
- Use the phone normally after removing the unwanted permission or app. Note whether the same notification returns and which app now sends it.
- If you entered a password into a suspicious page, change it from a different trusted device and review that account’s security activity. Never share the replacement password or verification code.
- If ads persist, an app cannot be removed, or the launcher remains changed, seek model-specific help before resetting. Back up important data first; factory reset removes local data and is not this guide’s first step.
Still not working? Know when to stop
Stop using a suspicious payment or password page. Contact the bank or account provider through a trusted channel if financial details or credentials were exposed. Seek device help for apps with administrator restrictions, work profiles or persistent lockouts; do not disable security controls blindly.
Write down the exact model and error message before contacting official support.

Frequently asked questions
Does “62 viruses” prove my phone is infected?
No. A web advertisement can display any number. Identify the sender and use trusted protection tools instead of the advertised scanner.
Do I need to buy an antivirus app?
Not to block website notifications. A separate security subscription is an optional prevention choice after the free checks, not proof of infection or a guaranteed repair.
Will clearing all browser data remove every problem?
No. It can sign you out and remove useful browser data while leaving an unwanted installed app untouched. Start with the specific notification permission.
When is a factory reset appropriate?
Only after a model-specific assessment and a checked backup when less disruptive steps fail. Know the account credentials needed after reset before any destructive action.
