To clean viruses from your phone, first boot into Safe Mode (Android) to stop malware, then uninstall suspicious apps and clear your browser cache, use built-in tools like Google Play Protect or reputable antivirus apps for scans, and if all else fails, perform a factory reset as a last resort after backing up important data.
You'll know your phone has a virus by symptoms like slow performance, rapid battery drain, high data usage, pop-up ads, strange apps, or unexpected messages to contacts, indicating malicious software is using your phone's resources or stealing data. To check, review your Settings > Apps for unfamiliar apps, monitor data/battery usage, and run a scan with a reputable mobile antivirus app like McAfee Security for Android from the Google Play Store or App Store.
Restart your phone normally & check apps
Clean a virus from an iPhone in 7 easy steps
You know your iPhone might have a virus or malware if you see unfamiliar apps, frequent crashes, rapid battery drain, overheating, excessive data usage, or persistent pop-up ads, especially if these symptoms appear together and your phone feels sluggish or acts unusually. While true viruses are rare on un-jailbroken iPhones, these signs point to malicious software, often from suspicious downloads, that can be detected by checking app behavior, data usage in Settings, and looking for unusual device management profiles.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
On an iPhone, dialing *#21# is a USSD code used to check the status of your unconditional call forwarding, revealing if your calls, SMS, or data are being redirected and to which number, without actually changing settings; it's a simple privacy check to see if someone has secretly set your phone to forward everything, though it doesn't detect advanced spyware. Dialing this code brings up a message from your carrier about your call forwarding status, often showing "Disabled" or a specific number if it's active.
*3001#12345#* on an iPhone activates the hidden Field Test Mode, a diagnostic tool for network engineers and power users to see detailed cellular data like signal strength (dBm), cell tower info, and network quality, accessible by dialing the code in the Phone app and pressing call, often after turning off Wi-Fi for accurate cellular readings.
If your phone loses battery, runs slowly, eats up your data, or otherwise starts performing poorly, it could be a sign that someone has unauthorized access to it. Check out this video for the 5 most common warning signs your phone is hacked, then jump down below to see even more signs.
To access Safety Check, use your iPhone to go to Settings > Privacy & Security > Safety Check. IMPORTANT: Before making changes or deleting information, consider potential impacts to your safety and privacy.
Factory resetting is the most drastic way to clear viruses on iPhone or iPad devices. Not only will a factory reset clear malware from your iPhone, but it will clear everything else too. We recommend that you try all other steps before restoring your device to a like-new state.
Simply restarting your phone won't remove malware from your device but restoring your device to its factory setting will. However, before you factory reset your phone and wipe all your data, let's try three simple steps first.
Run an antivirus scan
Conduct a full scan with your antivirus tool to detect any viruses or affected files present, then use the tool to delete them as required.
Do not use rubbing alcohol, paper towels, compressed air, dish soap or vinegar. All of these can damage your phone: Paper towels can scratch your screen, and vinegar could damage its coating. Do not use hand sanitizer on your phone screen, but do sanitize your hands before touching your phone.
Dial *#62# to see if any call forwarding is active on your iPhone. Check for a call forwarding number. Dial *#67# to see where your calls are being forwarded or redirected without your knowledge.
Call barring allows you to block certain types of incoming or outgoing calls. Dialing *#33# displays your device's current call barring status. If you're receiving excessive spam calls, enabling call barring can help prevent unwanted calls, including those from potential hackers.
##002# cancels all forwarding on many GSM networks worldwide. Dial ##002# and press call. You'll usually hear a confirmation message.
