A common question many iPhone users have is whether performing a factory reset, also known as wiping the iPhone, will remove any viruses or malware that may have infected the device. The quick answer is yes, wiping your iPhone will remove any viruses or malware, restoring the device to a clean state.
When you wipe your iPhone, it essentially erases the device and restores it to default factory settings, as if it was brand new. This process removes any files, data, apps, settings and accounts on your device. Importantly, it also removes any malicious software that may have found its way onto your device, including viruses, spyware, adware, ransomware, worms, trojans and more.
Resetting your iPhone to factory settings is therefore an effective way to disinfect your device if you suspect it has been compromised by malicious software. It essentially restores your iPhone to a blank slate, allowing you to start fresh.
How does wiping remove viruses from an iPhone?
To understand how wiping an iPhone removes viruses, it helps to know where viruses can hide and how wiping clears them out. When viruses infect an iPhone, they can lurk in a few key places:
– iOS system files and folders: Malware can sometimes inject code or make changes to iOS system files and folders that allow it to persist on the device.
– App data and files: Viruses can be bundled into apps and also create files that get stored in app-specific folders or databases on the device.
– iOS settings and configuration: Viruses may modify device settings or configurations to enable nefarious behavior.
– iCloud account: Some viruses link themselves to a user’s iCloud account as a way to reinfect the device even after it has been wiped.
When you wipe an iPhone, it resets all of these components that a virus might be hiding in:
– iOS is restored to the original factory version, removing any infected system files.
– All apps and their associated data/files are deleted.
– Settings and device configurations are reset.
– The link to the iCloud account is severed so any malicious backups will not transfer to the wiped device.
Essentially, a virus has nowhere left to hide when the whole iPhone is erased during a factory reset. Starting over with a brand new iOS install and blank slate for apps ensures the malware is gone.
When should you wipe your iPhone to remove a virus?
Wiping your iPhone is quite an aggressive measure so you don’t want to reset your device unnecessarily. Here are some situations when performing a factory reset is advisable to remove viruses or malware:
– You notice unusual behavior: If apps are crashing frequently, the device is running hot with high battery drain, strange pop-ups keep appearing or you see unusual activity, these could be signs of infection. Wiping the device can clear out the problem.
– Your iPhone was compromised: If you clicked on a malicious link, downloaded a fake app, fell victim to a scam or had your phone stolen, resetting it removes any viruses or vulnerabilities the attacker may have installed.
– You want to sell or give away your device: Performing a factory reset removes all your personal data but also any lingering malware before passing your device to someone else.
– As part of periodic maintenance: Some people wipe their iPhones every few months as part of routine security and maintenance. Resetting removes outdated apps, cleans up junk files and provides a fresh slate.
If you aren’t experiencing any issues with your iPhone, a periodic factory reset is likely unnecessary. But it’s still a handy tool to have in your backpocket if your device starts behaving strangely or you want to give it a clean bill of health.
How to wipe an iPhone
Performing a factory reset on an iPhone to wipe it fully is straightforward but does require you to take a couple steps:
1. Backup your iPhone data first
Before wiping your iPhone, it’s crucial to backup your personal data like your photos, messages, notes and app data. You have a few options:
– iCloud backup: You can backup your iPhone to iCloud by going to Settings > [your name] > iCloud > iCloud Backup and then choosing “Back Up Now”. This will store a copy of your data in iCloud that can be restored later.
– iTunes backup: Connect your iPhone to your computer and launch iTunes. Select your device and then under Backups choose “This Computer”. Then click “Backup Now” to save a local backup file to your computer.
– Mac Time Machine: If using a Mac, you can connect your iPhone and backup to Time Machine so you have a full system backup.
Be sure the backup fully completes before wiping your iPhone.
2. Sign out of iCloud and iTunes & App Store
Next, you’ll want to sign out of all accounts on your device:
– Go to Settings > [your name] and tap “Sign Out”.
– In Settings, tap iTunes & App Store and sign out of your Apple ID account.
This will unlink your personal accounts before wiping the device.
3. Factory reset the iPhone
The final step is the actual reset process. To wipe the iPhone:
– Go to Settings > General > Reset
– Tap “Erase All Content and Settings”
– If prompted, enter your passcode
– Confirm that you want to erase the device by tapping “Erase”
Your iPhone will reboot into a clean freshly installed state without any of your old data or accounts.
What data does wiping an iPhone delete?
When you factory reset your iPhone, it deletes all of the following:
– Apps and app data
– Messages, call logs and voicemail
– Contacts and calendars
– Photos and videos
– Music, books and other media
– Home screen customizations and settings
– iCloud and iTunes & App Store accounts
– Passwords and accounts
– Apple Pay information
Essentially everything stored locally on the device is erased. However, any data backed up to iCloud or your computer will remain intact and can be restored after wiping the phone.
Some people reset the iPhone but expect certain data like photos or messages to remain. This is not the case – a factory reset wipes out everything. So backups are crucial.
Will wiping an iPhone delete everything for sure?
Performing a factory reset on your iPhone will delete all the data stored on that device 100%. However, there are a couple of scenarios where wiping the phone might not remove absolutely everything:
– iCloud backup reinstalls apps: When you setup your wiped iPhone again and sign into your iCloud account, it can automatically reinstall apps and personal data from the iCloud backup. To get a 100% fresh start, use a new iCloud account instead.
– Persistent malware: Sophisticated viruses may be able to survive a wipe if they are at the system level, though this is very rare. Usually resetting an iPhone will kill any standard virus.
– Restoring from a backup: If you restore your apps and data onto the wiped iPhone from an iTunes or iCloud backup, any malware living in that old backup could find its way onto the device again. Doing a clean install and setup is safest.
But in most cases, factory resetting an iPhone will thoroughly purge any viruses, malware or other infections present on the device, leaving it like new. Just be cautious about backups reinstalling apps or data that could carry malicious code.
Can wiping your iPhone get rid of existing viruses in iCloud?
If your iPhone has been infected by a virus, it’s possible the virus spread via iCloud and infected your entire account. So when you wipe your iPhone, does resetting remove the virus copies lurking in iCloud?
Unfortunately, simply wiping your iPhone does not remove viruses stored in your iCloud account. iCloud is persisted online and tied to your Apple ID. Since wiping your device does not touch your iCloud data, any infected backups or apps could easily reinfect your iPhone.
To fully remove viruses from iCloud:
– Reset your iPhone to unlink it from iCloud and wipe local data.
– Go to icloud.com and sign into your account.
– Manually inspect and delete any suspicious backups, documents or data in iCloud Drive.
– Delete and reinstall any possibly infected apps connected to your Apple ID.
– Change your iCloud password to revoke access.
– Enable two-factor authentication for added security.
This scrubs your iCloud account and removes viruses lurking there so they cannot spread back to your iPhone. Going forward, use a brand new iCloud account to be extra safe.
Common Concerns
Here are some frequent concerns and questions that arise when wiping an iPhone to remove viruses:
Will I lose all my data if I wipe my iPhone?
Yes, performing a factory reset on your iPhone will erase all locally stored data and settings. However, anything backed up to iCloud or your computer beforehand can be restored onto your device after wiping it. So make current backups.
Can I wipe just some data, not everything?
Unfortunately there is no way to selectively wipe only some data or apps from your iPhone. Performing a factory reset erases everything on the device indiscriminately. You’ll need to be prepared to lose all local data.
Is it guaranteed to remove any virus or malware?
Resetting your iPhone to factory default settings is very highly likely to remove any viruses or malware, as it erases everywhere they could be hiding. However nothing is 100% guaranteed against the most advanced threats. But for most purposes, wiping an iPhone will clean it of infections.
How long will it take to wipe my iPhone?
The factory reset process itself generally only takes a few minutes at most. However, you’ll need to spend time backing up your iPhone data beforehand, and restoring that data afterwards if you wish. So factor in up to an hour or more for the end-to-end process.
Will I need to reactivate my iPhone after wiping it?
If your iPhone is carrier locked, you may need to contact your carrier to reactivate your device after wiping it, as the reset process deactivates the existing activation. Unlocked iPhones can be activated normally like new.
Is there a way to wipe an iPhone without a passcode?
If you’ve forgotten your passcode, you cannot perform a factory reset without connecting your iPhone to a trusted computer authorized to access the device. This bypasses the need for a passcode to initiate the wipe.
