![]() Go to Settings > Safari > Clear History and Website Data, then tap Clear History and Data to confirm. Here's a quick tip that may resolve web page redirect problems. Even if you do decide to delete the app permanently, however, remember that you can check in with the developers from time to time and see if a satisfactory update has materialised. If the problem disappears then you've found your culprit, and it's time to decide if you can manage without the app in the long term. They may be able to offer a solution right away, but even if they can't, they are more likely to find a fix if they know about it.Īssuming that updating the app doesn't solve the problem, uninstall it and try to manage without for a while. If the devs are contactable then you should report the issue to them. Also check the app's website (if it has one) and/or the developers' Twitter feed (if they have one) to see if the issue has been reported or discussed in those places. If you think one app is the problem, first of all have a look to see if an updated version of the app is available, since the problem may have been noticed and fixed. ![]() The usual giveaway sign is that, when you've got that app open, you will periodically be redirected to a web page, or to the App Store, without your permission. It's usually obvious when one particular app is the culprit, because you only have problems when using it. The crooks thus gain the ability to redirect you to a dodgy website when you use the app that was built using the compromised tool. This doesn't necessarily mean the app is bad or that the developers are at fault conversely, the fact that an app is legitimate or was made by a reputable company doesn't mean it can't be hijacked by malware or hackers.īecause hackers cannot break into iOS itself, one of their most common strategies is to crack a developer kit, which may in turn be used by unwitting app developers. Rather than a virus affecting iOS itself, it's possible that you've simply got a problem app. Is a compromised app causing the problem? In any of these cases we would take the device to an Apple Genius Bar. It's extremely unlikely that malware has penetrated to the heart of the operating system and is causing problems throughout the system this would be essentially unprecedented. If the problem continues to happen no matter which apps are open, the chances are that your device is misbehaving because of a hardware problem, or because of an iOS change that you're not used to yet, or because you or another user of the device has changed a setting, perhaps inadvertently. See our full list of the best antivirus here. Bitdefender Total Security is also an option for both Mac and PC users that adds protection for iOS devices, and throws a VPN into the mix too. For example, Intego's Mac Internet Security can scan for viruses on iOS devices. ![]() In the past, you may have been able to find the root of the problem using a dedicated antivirus app for iOS, but Apple in 2015 chose to eliminate the category of antivirus and antimalware products from its App Store. Common behaviour exhibited by apps that have been hijacked include redirecting you to an unfamiliar web page in Safari, and opening the App Store without permission. Have you jailbroken your device? And if so, have you installed an application from a non-official source whose authenticity is questionable? If the answer to both is yes, you may have a malicious piece of software on your device, and should attempt to isolate and uninstall the culprit.ĭoes the unexpected behaviour manifest itself when you use certain apps only? If so - and particularly if it's only one app - then you're probably looking at an app-specific issue, and we'll deal with this in a moment. The main questions when trying to work out what has happened to your malfunctioning iPhone or iPad are these: In either case, however, iOS's sandbox structure should prevent the malware attack from getting access to other applications (in order to spread itself) or to the underlying operating system. And although compromised apps should be caught at the App Store's approval stage, those who have jailbroken their devices are able to download apps from non-official sources, which may mean they've inadvertently installed something dangerous. The iOS platform has seen a number of attacks that fit the first definition, when attackers have inserted malicious code into respectable apps or hijacked the developer tool used to create them. Technically speaking, a virus is a piece of code that inserts itself into another program, whereas a worm is a standalone program in its own right both seek to propagate themselves by hijacking messaging applications or via social engineering. ![]()
