You may have been infected with the AppLock adware virus. Here's a look at what's behind this annoying mobile virus and how to protect yourself against it. AppLock affects iOS devices, including all variants of iPhones and iPads. It can also cause some issues for a cloud-connected macOS device. Lifewire / Theresa Chiechi What Is the AppLock Virus? The AppLock virus is an annoying form of malware that affects Apple-based devices. It shows users excessive numbers of ads and sometimes causes page redirects to other sites. On its own, the AppLock virus is just an irritant. Still, it can pave the way for more nefarious online threats to arrive on your system via unsafe advertisements a user unwittingly opens. How Does AppLock Work? AppLock is a browser hijacker, so it works by constantly displaying advertisements on your iPhone or iPad. It's not as dangerous as a "true" virus or malware, but it's very annoying and can leave your system less secure. AppLock may expose you to ransomware threats and other issues by opening up so many pop-ups and page redirects that you can end up mistakenly clicking on an unsafe ad. AppLock is also quite likely spying on your activities, recording your browsing history and search queries in a bid to figure out what ads are most likely to attract your attention. AppLock is easy to spot because it bombards you with copious pop-up banners and advertisements, and it may change the default search engine on your browser. The ads tend to be for unfamiliar, suspicious-sounding websites. While AppLock won't slow down your system like a computer-based form of adware, it will be very annoying as you try to browse other websites. How Did I Get the AppLock Virus? One of the easiest ways to make your iOS device open to viruses and malware is by jailbreaking it. While there are some advantages, jailbreaking immediately makes your iPhone and iPad less secure. It's also possible to acquire the AppLock virus by downloading files from illicit sources and viewing them on your iOS device. How Do I Get Rid of the AppLock Virus? It's important to shut down AppLock so the problems it causes don't escalate and get worse. One of the most effective ways of getting rid of the AppLock adware virus is to use iOS-based antivirus software.
