iPhones are assumed to be one of the securest devices, especially when compared to their peers. While they are secure, they are not ibvicinble and are prone to security vulnerabilities. So if your iPhone is acting wierd and overheating, and acting on its own like displaying random pop-ups or installing apps, don’t panic.
In this post we will show you fast and effective solutions to clean things up. But first,
How to Tell if Your iPhone Has a Virus?
As unlikely as it sounds, iPhones can get infected with viruses. Apple’s closed ecosystem and strict App Store rules make it rare, but it can happen. The most common risks are using third-party app stores or owning a jailbroken device.
If you are not sure if your phone is infected? Watch out for these signs:
If your device has been behaving strangely, it may not just be a software bug. Watch out for these warning signs:
- Battery draining fast: Check Battery settings for apps using unusual power. The same is true for data spikes. If you are seeing your data capacity getting over quickly, you know it’s a virus.
- Overheating: If your phone is getting hot (or warm), even when idle, it may signal something is running in the background.
- Crashes or sluggishness: iPhones, especially the newer ones, are known to fly through common tasks and multitasking. So, if you notice frequent lags and slowdowns, it could indicate deeper issues.
The rule of thumb is to watch for warning signs early. If you are still unsure, a quick restart can help. Often, restarting is enough to stop a stuck or faulty background process causing issues.
At the same time, if you have recently installed any new apps, consider removing them completely. Even though the App Store is strict, a problematic app can sometimes slip through and cause issues on your device.
How to Remove Virus from iPhone
If any of the above issues sound familiar, take the following steps to clean your device.
1. Update iOS and Apps
If you are unsure if your iPhone is updated, you can check the same by navigating to Settings > General. Next, tap Software Update. If you see an update available, simply tap Download and Install.
Post iOS 26, you will also need to update your apps manually. To do so, go to the App Store and tap your profile icon in the top right corner. Scroll down and tap Update All to install all available app updates.
Do note that apps, as well as your phone, should be kept updated as they keep you safe from known vulnerabilities. Malware often targets outdated software.
2. Clear Safari History
One of the other places to check is your browser if you have seen strange pop-ups or redirects appearing. To fix this, you will need to clear Safari’s (or your preferred browser’s) history to prevent them from recurring.
For Safari:
Navigate to Settings > Apps, and scroll down until you see the option for Safari. Tap to open it.
Next, scroll down until you see Clear History and Website Data, choose the desired time frame, and confirm your action to clear your browser of cache, cookies, and saved web data.
That said, your passwords and bookmarks will remain unaffected.
For Chrome:
Open the Chrome app on your iPhone. Tap the three-dot menu at the bottom right and select History.
Then tap Clear Browsing Data, choose the data types you want to remove (like cookies, cached images, and browsing history), select the desired time range, and confirm by tapping Clear Browsing Data.
3. Reset All Settings (If Problems Persist)
If your iPhone still feels weird, even after following the above steps, you can try resetting the settings. The advantage is that it helps preserve your data, such as photos, files, and apps.
To do so, go to Settings and tap General. Scroll down and select Transfer or Reset iPhone, then tap Reset. Choose Reset All Settings, and enter your passcode to confirm the action.
This process resets your Wi-Fi passwords, privacy settings, keyboard dictionary, and more, but keeps your data intact.
4. Restore From an Earlier Backup
As a last resort, you can also restore an old version of your iPhone backup. This should be your go-to step if the issues relating to your phone has started after installing a new app/file or changing any of your phone’s settings.
To do so, follow the steps below,
Open Settings on your iPhone and tap on your Apple ID at the top. Now, navigate to iCloud > iCloud Backup and check the timestamp of your last successful backup.
Once done, head back to General settings > Transfer or Reset iPhone, then tap Erase All Content and Settings and confirm your decision. After your iPhone restarts, follow the on-screen setup instructions. When prompted, choose either Restore from iCloud Backup or Restore from Mac or PC, and select a backup that was created before the issue started.
It’s worth noting that installing a dedicated anti-virus also does not work in most cases since the iPhone’s OS is designed with sandboxing in mind. Hence, each app runs in its own restricted environment, and this makes it challenging for antivirus apps to scan your device in the same way they scan Android phones or even your PC.
Closing Note
If you have tried everything and the problem still persists, wiping your iPhone completely is the most effective solution. A factory reset will remove any lingering malware or suspicious activity and return the device to its original state. However, prevention is always better than a cure.
To stay protected, regularly update your iOS and apps to guard against the latest security vulnerabilities. Also, when using public Wi-Fi, a VPN can help shield your data from potential interception. You should also enable two-factor authentication for your Apple ID to add an extra layer of account security. Finally, periodically review app permissions and revoke access for any apps you no longer use or trust to maintain a clean and secure device.
