Key points
iOS is a generally secure operating system, specially programmed to allow the Apple devices on which it is installed to generally be threatened. The problem is only one: if you intend to rely only on what an iPhone by offers, it is better to change your mind and consider the idea of relying on specific tools.
Jailbreak makes iPhone more vulnerable to viruses
When your iPhone, regardless of the model, behaves strangely, the time has come to ask yourself if it is affected by a virus: although an Android system is more at risk of flaws that allow infection, even iOS is not totally immunized against this type of attack.
Viruses that affect operating systems are portions of malicious code capable of self-replicating. If a normal iPhone, updated, does not risk very much, what can happen if it has been subjected to a jailbreak procedure is different.
Jailbreaking an iPhone allows you to illegally obtain root privileges capable of avoiding the security restrictions that usually limit the functionality of the software, but at the same time make the system vulnerable. It is no coincidence that Apple condemns this practice by constantly trying to correct the vulnerabilities that allow the procedure to be carried out.
Therefore, iPhones can actually be infected by viruses, even more so if the device system is modified and that it is important to be proactive in ensuring the greatest possible security for your Apple smartphone.
Effects of a virus on the iPhone
The operating system of the iPhone is designed to defend the device from virus attacks: this does not mean, it should be emphasized, that the iPhone can become infected. When such a device is hit by a computer virus, the risk is that it can cause damage and delete or steal data.
Generally a computer virus, when it hits a smartphone, is then able to communicate with all the programs that make up the system: iOS is programmed to make this step very difficult: it has in fact been designed in such a way that each application runs in a space separate virtual.
Since the interactions between apps are limited, the virus is unlikely to spread: it is also of great help that every application that is downloaded to an iPhone comes from the App Store, where they are strictly controlled.
Although any iPhone malfunctions can be linked to different causes, it is important to pay attention to some signs that could indicate the presence of a virus: unknown apps installed without your knowledge, increased battery consumption, applications that freeze without reason, a cost plus telephone charges and the display of pop-ups while browsing.
How to fight viruses on iPhones:
While it is rare for a virus to infect an iPhone, especially if a jailbreak is performed, occurrence is not impossible. How to fight the problem? Through specially designed antivirus. As with any other device regardless of the operating system, if a computer virus strikes, you need a "medicine" that can eliminate it.
A list of such services is here via the link, available to those who need an effective tool to care for their device.
When it comes to antivirus for iPhone, although infection is considered unlikely, there are many possibilities available to users. Downloading and running the one that best suits your needs is one of the countless and most complete solutions, especially since its presence inside the iPhone allows you to keep iOS constantly protected.
But there is also the option of manual removal if you suspect that you have been infected with a virus and are having difficulty downloading the antivirus application. The first thing to do is to eliminate the applications that appear suspicious: in particular those that are not recognized or that have been actively downloaded, then continuing with the deletion of data and history. To do this, simply enter the "Settings" menu, selecting first "Safari" and then "Clear website and history data".
Then you have to restart the iPhone, holding down the power key and scrolling to turn off. To restart it is necessary to hold it down again. Among the possible application solutions there is also the installation of previous backups, free of malware or the restoration of factory settings. If even in this way the problem is not solved, the use of an antivirus is necessary and essential.
In conclusion, although iOS may have been designed to keep viruses out of the iPhone, especially if the user decides to appropriate root permissions with the Jailbreak, it becomes a device vulnerable to this type of attack.
Alone it will not always have the ability to defend itself adequately: it is therefore good to pay close attention to what you download and where you browse, but above all to equip yourself with effective antivirus.
