iPhones are less likely to be infected by viruses but not without risks, especially older models or jailbreak devices are more susceptible to impact. If your phone has problems such as stuttering, advertising pop-ups, abnormal battery power consumption, etc., you can troubleshoot them as follows: 1. Check whether there are suspicious applications, especially programs that are not installed on the App Store, to see if there are unfamiliar or strange-named apps. Jailbreaking devices need to be checked carefully. Uncertain applications can be tried to uninstall them; 2. Check whether Safari and other browsers automatically jump to abnormal websites or frequently pop up advertisement pages disguised as "poisoning warnings", and clear the browser cache or temporarily use Safari test; 3. Use formal security tools such as Lookout, Avira Mobile Security, and Clario AntiSpy to scan for potential threats, and be careful to download relevant software from the App Store only; 4. Pay attention to system updates, upgrade to the latest iOS version in time, pay attention to abnormal prompts such as "unauthorized certificates", and avoid clicking suspicious links in text messages or emails. Good use habits are the key to preventing viruses.
The iPhone is indeed less likely to be infected by a virus than Android, but it is not completely immune. Especially for some old models or jailbroken devices, the risks will be higher. If you find abnormal behaviors in your phone, such as lag, pop-up advertisements, abnormal battery consumption, etc., you can check them according to the following methods.
1. Check if there are any suspicious apps
Some malware is installed in disguise as normal apps, especially programs installed from non-App Store channels.
- See if there are any apps you don't remember downloading
- Check whether the icons and names of certain apps are strange (such as "System Tools" and "Cleaning Assistant" that sound very general)
- If you have jailbroken from your phone, this type of problem is more likely to occur. It is recommended to check this type of application first
If you encounter uncertain apps, you can uninstall them directly and try it. If the phone status improves after uninstalling, it is likely that it is its problem.
2. Check whether there are any exceptions in Safari and other browsers
Sometimes the virus is spread not through the app, but through the web page, especially if you accidentally click phishing links or malicious ads in Safari.
- See if the browser will automatically jump to a strange website
- Whether ad pages pop up frequently, especially those warnings that disguise as "your iPhone is poisoned"
- You can try to clear the browser cache, path: Settings > Safari > Clear history and website data
In addition, if you use third-party browsers like Chrome or Firefox, you can also consider temporarily changing to Safari to see if the problem still exists.
3. Use professional tools to scan
Although the iOS system itself has a security mechanism, you can use some formal security apps to assist in detection:
- Lookout : Can scan for vulnerabilities and suspicious behavior on your device
- Avira Mobile Security : Provides privacy leak reminders and malicious website protection
- Clario AntiSpy : suitable for users who are worried about being monitored, and can scan device connections
These apps cannot be directly anti-virus, but can help you identify potential threats. When using it, be careful to download it only from the App Store, and do not use so-called "antivirus software" of unknown origin.
4. Pay attention to system prompts and updates
Apple's system will regularly push security updates. If your system version is too old, there may be unfixed vulnerabilities.
- Settings > General > Software Updates to see if there are any upgradeable versions
- If you receive a prompt like "Unauthorized Certificate" or "Configuration File has been changed", you should pay attention to it, which may be a malicious setting modification.
In addition, do not click on links in text messages or emails casually, especially content such as "winning notice" and "express delivery exception". Many of them are means to induce access to malicious websites.
Basically these common inspection methods. Although iPhones are not easily poisoned, it does not mean that there is no problem at all. Developing good usage habits in daily life, such as not clicking on links or installing apps from unknown sources at will, which is more important than remediation afterwards.
