Masstrk is a potentially unwanted iPhone app that can also be found on iPads. The app is known to impact the device’s performance by showing intrusive pop-ups, banners, and hard-to-remove advertisements on the screen. Masstrk may also hijack the main web browser and force it to redirect users to random sites as well as keep track of various browsing-related data.
In general, security researchers classify apps like Masstrk as browser hijackers and don’t consider them as dangerous viruses or direct security threats. The primary objective of most browser hijackers is to promote products/sites and to raise revenue from clicks on paid advertisements (The Pay-Per-Click method).
The Update Masstrk Virus
A hijacker such as the Update Masstrk virus, however, could render your iPhone or iPad susceptible to various online risks such as phishing pages, misleading ads, online scams, and even malware.
The Masstrk Malware
One of the key issues with applications such as the Masstrk malware is that once installed, they typically gain a wide range of system permissions that allows them to make changes to the main web browser (change its homepage, install extensions, replace the search engine, etc.) and also add new features without requesting approval from the user.
In addition to that, such apps may use an auto-redirect function to reroute the user’s searches to different sponsored pages, some of which may not be very reliable.
Naturally, to avoid any problems, you have the option to remove Masstrk immediately with the help of the removal guide below. If you decide to take this course, ensure that you carefully follow the steps shown in the guide to successfully remove all components linked to the hijacker from your iPhone or iPad.
Remove Masstrk iPhone Calendar Virus
If you have an iPhone virus, continue with the guide below.
If you have an Android virus, please use our Android Malware Removal guide.
If you have a Mac virus, please use our How to remove Ads on Mac guide.
If you have a Windows virus, please use our Windows Virus Removal guide.
First you need to close all pop-ups that are currently open.
- If the pop-up has a checkbox named “Don’t show more alerts from this webpage” click on the checkbox before closing the Ad.
- If a Block Alerts button happens to appear after you shut down a pop-up on your iPhone, iPad, or iPod touch tab that button to stop receiving alerts from the same page.
In case that a pop-up fails to close after performing the above operations:
- On your Mac you should make your Safari browser close forcibly by pressing Command-Option-Esc. Select Safari from the list of Apps and force close it. After you force close it you need to restart Safari, but please hold the shift button while it starts. This will prevent any pesky Ads from opening automatically.
- On your iPhone, iPad, or iPod touch you can do the same by pressing the home button twice in a quick succession. You’ll then see a preview of all apps that have been recently used. Swipe left to find Safari and then swipe up on the app’s preview to close it forcibly In order to prevent Safari from opening unwanted windows on startup go to Settings->Safari and Clear History, as well as Website Data. This will also clear your browser history and cookies so keep that in mind and export them if you want to keep them.
Choose Preferences from the Safari menu. Then do the following:
- Select the Security icon and then click on “Block pop-up windows“. This should stop many types of pop-ups from appearing.
- Next check on your homepage and the settings for the search engines. Adware likes messing with those. We can not provide more specific instructions for this, as you may be using many different browsers.
- Select the General icon and look at the Homepage field. It should either be empty or filled with the address of the Homepage you want.
- Follow up on the Search icon. Again it should be either the default search engine or any that you have set for yourself. Note that in some versions of Safari these settings are found in the General panel/
Open Safari and click on the Extensions button. Note that Adware use extensions almost exclusively to inject the pop-up Ads into your browser. Any extension on this list that you do not remember installing yourself is likely planted there by the Adware. Remove ALL extensions you are unfamiliar with.
