Usually not. Consumer antivirus apps and Android app scanners can find many malicious applications and known indicators, but they cannot certify that a phone is free of zero-click spyware. A zero-click exploit abuses a software vulnerability—often in messaging or media processing—without requiring you to tap a link, install an app or open an attachment.
A clean scan is useful evidence against some common malware, not proof that a sophisticated, targeted exploit has never compromised the device. The right response depends on your risk: ordinary users should reduce attack surface with updates and built-in protections; people with credible evidence of targeted surveillance need specialist forensic help.
What “zero-click” spyware means
The Cybersecurity and Infrastructure Security Agency (CISA) uses “zero-click” for exploits that require no direct action from the device owner. The attacker may send a specially crafted message, image, video, call invitation or other network data. A vulnerable component processes that data automatically, and the exploit runs before you have a chance to reject it.
Google Project Zero documented an NSO Pegasus iMessage exploit that could target a phone number or Apple ID and execute without the victim clicking a link. Project Zero researchers Ian Beer and Samuel Groß described the problem starkly: “Short of not using a device, there is no way to prevent exploitation by a zero-click exploit; it’s a weapon against which there is no defense.” That statement describes the difficulty of stopping an unknown exploit chain, not the usefulness of routine security updates or device hardening.

Zero-click versus ordinary spyware
Many consumer spyware infections still depend on a visible step: installing a fake utility, sideloading an altered package, approving a profile or opening a malicious document. Antivirus and app scanners are well suited to those cases. Zero-click attacks are different because the initial code execution can happen inside a trusted system service. There may be no suspicious app icon, permission prompt or download for a scanner to inspect.
Why ordinary antivirus has a blind spot
Mobile antivirus products generally look for malicious applications, recognizable files, suspicious behavior and previously documented indicators. Google Play Protect illustrates the model: it checks apps before installation, scans installed apps periodically, and can warn, disable or remove known harmful applications, including apps installed from outside Google Play.
A zero-click chain can run through a vulnerable messaging, image, video or voice-processing component before any malicious app is installed. Code may execute in memory, exploit a privilege boundary and then erase or minimize artifacts. App-scanning coverage therefore cannot be treated as full operating-system compromise detection.

What a clean scan does—and does not—establish
- It can lower the likelihood that a known malicious app or recognizable trojan is installed.
- It cannot rule out a novel exploit for which no detection signature exists.
- It cannot prove that memory-only code, a compromised system service or a temporary exploit left no trace.
- It cannot establish that a targeted attacker never accessed the device.
The FBI’s general consumer guidance says people may consider mobile antivirus for additional security. That is sensible hygiene, but it is not a claim that antivirus reliably finds novel, targeted, memory-only or system-level zero-click spyware.

How the main protection layers compare
Protection tools answer different questions. Prevention controls reduce the chance of compromise; detection tools look for known evidence afterward. The table shows the practical boundary between them.
| Protection | Primary job | Strongest coverage | What it cannot prove | Operational trade-off |
|---|---|---|---|---|
| Mobile antivirus | Scan apps, files and sometimes device behavior | Known malicious apps, trojans and recognizable indicators | That an unknown exploit chain or system-level implant is absent | May use battery, storage and permissions; effectiveness varies by product |
| Google Play Protect | Pre-install and periodic app checks | Harmful apps from Google Play and other sources, when detectable | That Android has not been compromised through a vulnerable system component | Automatic protection with little user effort |
| Android Advanced Protection | Stronger defaults around scanning and installation sources | Reducing malicious-app and sideloading risk | Retroactive proof that an unknown exploit did not run | Restricts some installation paths and other high-risk actions |
| Apple threat notification | High-confidence, targeted warning based on Apple intelligence and investigation | Individually targeted mercenary-spyware cases Apple can substantiate | Absolute certainty, or a clean bill of health when no notification arrives | Rare and targeted; not a routine antivirus scan |
| Amnesty International Mobile Verification Toolkit (MVT) | Consent-based forensic examination of Android and iOS data | Known forensic traces and indicators associated with documented attacks | All future exploit chains or compromises that leave no detectable evidence | Results require specialist interpretation and careful evidence handling |
What an iPhone can tell you
Apple describes mercenary-spyware attacks as exceptionally sophisticated, potentially costing millions of dollars and often having a short operational shelf life. Since 2021, Apple says it has notified users in more than 150 countries. Those figures are Apple’s 2026 characterization, not a count of every infected phone.
Apple threat notifications
An Apple threat notification is a high-confidence alert that Apple believes a user was individually targeted. Apple says its investigations can never achieve absolute certainty, so the alert is not mathematical proof; it is nevertheless a serious warning based on internal threat intelligence and investigation.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsA genuine notification appears on the iPhone Lock Screen and in Settings, is sent by email, and remains visible after signing in directly at account.apple.com. Apple says its notifications never ask for your password, verification codes, links, files, apps or configuration profiles. Do not use contact details supplied in a suspicious message to “verify” an alert.

What to do after a notification
- Open the notification through the iPhone’s Lock Screen or Settings, then independently sign in at
account.apple.comto confirm it. - Follow Apple’s instructions and enable Lockdown Mode when Apple advises it.
- Stop using the phone for sensitive conversations until a qualified responder gives you a plan.
- Contact a specialist organization. Apple specifically directs notified users to Access Now’s Digital Security Helpline.
Apple’s platform defenses, including BlastDoor and Lockdown Mode, reduce the attack surface for sophisticated zero-click threats. Lockdown Mode intentionally disables or limits some features, so Apple recommends it for a very small, high-risk population rather than as a default setting for everyone. Turning it on now can reduce future exposure; it cannot retroactively prove that a prior compromise did not occur.
What Android can tell you
Google’s Android security documentation says Play Protect checks apps from Google Play and other sources, performs periodic scans, and may warn, disable or remove harmful applications. Keep it enabled, especially if you ever install software outside the official store.
Advanced Protection adds stronger controls, including automatic scanning and restrictions on many installations from outside Google Play. Those settings lower the probability of a malicious-app infection. They do not demonstrate that an unknown exploit has not compromised Android through a messaging, media or system component.

If you have credible reasons to suspect targeted spyware
Credible reasons might include an Apple threat notification, evidence that a high-risk contact was targeted, or an incident-response professional identifying suspicious indicators. A vague battery change or a single crash is not enough to diagnose zero-click spyware.
Preserve evidence before changing the phone
- Move sensitive conversations to a different, trusted device and avoid discussing the investigation on the suspected phone.
- Record dates, messages, notification screens and unusual events. Preserve original files rather than forwarding or editing them.
- Do not factory-reset, erase backups or install random “spyware removal” tools.
- If evidence may matter, ask a qualified responder whether updating or changing settings would destroy useful artifacts. Follow their sequence rather than improvising.
- Contact a reputable digital-security organization or mobile incident-response specialist.
Forensic checking with MVT
Amnesty International’s Mobile Verification Toolkit (MVT) supports consensual forensic analysis of iOS and Android devices. It compares available device data with known indicators and can identify traces associated with documented compromises. MVT is not a magic scanner: results require careful interpretation, indicators change, and a negative result is not a universal guarantee that an exploit chain never ran.

Patch quickly
Install operating-system and app updates promptly. Patches close known vulnerabilities, including flaws that attackers may otherwise exploit automatically. Updating cannot undo a previous compromise, but it is the most important routine measure against known attack paths.
Strengthen accounts and the lock screen
- Use a long device passcode rather than an easily guessed pattern.
- Use unique passwords for important accounts and turn on two-factor authentication.
- Review account and device-linking prompts; reject requests you did not initiate.
Reduce malicious-app risk on Android
- Keep Google Play Protect enabled.
- Prefer trusted app stores and avoid unsolicited installation files.
- Consider Android Advanced Protection if your risk justifies its restrictions.
Handle unexpected content carefully
Do not open unexpected links or attachments, even though zero-click attacks do not require a click. Social-engineering attacks remain common, and a cautious response prevents the separate class of infections that antivirus can often detect.

Consider Lockdown Mode only for a high-risk profile
On iPhone, Lockdown Mode is intended for people whose work, identity or public role makes targeted mercenary spyware plausible. It reduces attack surface by limiting certain message, web, attachment and communication features, with corresponding usability costs. It is a risk-based control, not a diagnostic test.
How to interpret the result you have
| Your situation | What a scan or alert means | Best next step |
|---|---|---|
| Routine security check, no specific warning | A clean antivirus or Play Protect result lowers the chance of a known malicious app | Keep updates and protections enabled; do not claim the phone is forensically clean |
| Concern after sideloading an unfamiliar app | App scanning is relevant and may find the unwanted package | Remove the app if identified, change affected credentials and seek help if account abuse continues |
| High-risk person with credible targeting evidence | A normal scan is insufficient | Stop sensitive use, preserve evidence and contact a specialist responder |
| Apple threat notification | High-confidence targeted warning, not absolute proof | Verify directly at account.apple.com, follow Apple’s instructions and seek expert help |
Frequently misunderstood points
Can antivirus detect Pegasus?
It may detect a related malicious app or a known forensic indicator, but it cannot reliably detect every Pegasus-class zero-click compromise. A clean result is not a guarantee.
Will a phone scan find spyware that never required a click?
Only if the scan has a recognizable artifact to inspect and the relevant data is accessible. Exploit code that runs in a vulnerable service, remains in memory or uses a newly discovered chain may evade an ordinary scan.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Does Play Protect detect spyware?
Play Protect detects many harmful applications, including some spyware and trojans, from Google Play and other sources. Its documented role is app detection; it is not proof that Android’s operating system has never been exploited.
How do I know if my iPhone was hacked without clicking anything?
You cannot establish that from the absence of symptoms or a consumer scan. Check for an authentic Apple threat notification, preserve evidence if you have credible targeting reasons, and obtain specialist forensic assistance.
What should I do if I get an Apple threat notification?
Verify it through the Lock Screen, Settings and a direct sign-in at account.apple.com. Do not follow links or provide credentials in the message. Follow Apple’s instructions, consider Lockdown Mode when advised and contact a qualified responder.
