The iPhone continues to evolve year after year, boasting a wide range of features and is widely regarded as having excellent security. This makes it incredibly convenient for tasks like making payments or storing important data. However, even the iPhone, known for its strong security, can sometimes become infected with viruses. Therefore, let’s explore methods for checking your iPhone for viruses and measures to prevent virus infections.

How to Check if Your iPhone Has a Virus
If your iPhone becomes infected with a virus, various symptoms may appear. Here’s how to check for iPhone viruses yourself.
An unfamiliar App is installed on my device.
Some viruses install apps for hacking or remote control without your permission. If you find an unfamiliar app on your home screen, delete it immediately without opening it.
Furthermore, leaving such apps unattended could lead to significant damage without your knowledge. Regularly manage your apps and check for any suspicious ones.
Communication data usage increases
When an iPhone becomes infected with a virus, the virus conducts a large amount of suspicious communication in the background, causing an unnatural increase in data usage.
If you’ve been watching more videos than usual, installing new apps, or using the internet a lot, that’s no problem. However, if you’re using your device the same way as always but notice a significant increase in your data usage, suspect a virus infection.
The battery is draining quickly.
ウイルスが活発に活動することによって、勝手に通信が行われバッテリーが消費しやすくなります。バッテリーの劣化の可能性もありますが、「以前よりバッテリーの消費が以上に速い」「なにもしていないのに、バッテリーがすぐなくなる」などの症状が見られる場合は、注意が必要です。
Repeated Unintended Restarts
If your iPhone becomes infected with a virus, unauthorized communications occur, causing instability. As a result, the device may repeatedly restart on its own, or Apps may force quit unexpectedly. If these symptoms persist, your iPhone may be experiencing issues due to a virus or malware infection.
Paragraph
iPhone body overheating
Similar to excessive battery drain or repeated spontaneous reboots, your iPhone’s body may overheat. If it feels hot despite no unusual activity, be cautious—this likely indicates a virus infection placing strain on your device.
iPhone virus scanning is not possible
iOS, the iPhone’s operating system, lacks built-in virus scanning functionality. Therefore, you cannot check whether your iPhone is infected with a virus or if data is leaking. In other words, the only way to check for viruses on an iPhone is through the self-checks mentioned earlier.
The reason for this is that the iOS system is not publicly available, and iOS itself is designed to prevent virus scanning, making it impossible for anyone other than Apple to perform virus checks.
Measures to Prevent Virus Infection
The iPhone does not have a virus scanning function.
Updating iOS newest version
Updating your iPhone’s iOS keeps both the operating system and security patches current. This fixes vulnerabilities and enhances protection against viruses. Consequently, it maintains the latest, highest level of security capabilities, making it less susceptible to virus infections.
Do not download apps from sources other than the App Store
Only apps that have passed Apple’s rigorous screening process are published on the App Store, ensuring the apps provided are highly secure and reliable. This strict screening includes virus standards, making the possibility of virus infection from App Store apps extremely low.
Use security software
Using security software is the most effective preventive measure against virus infection. It covers security aspects that iOS alone cannot fully protect, minimizing the risk of virus infection.
Paragraph
That said, security software cannot perform virus scans. However, it strengthens your iPhone’s security, providing a safe environment and regular preventive measures! If you’re concerned about virus infection on your iPhone, we highly recommend using security software.
