Msgstars iPhone


Msgstars is a browser-hijacking app for iOS devices that will automatically redirect your browser to different promoted sites and change its default search engine and homepage. Msgstars will also put pop-up banners on your screen with the goal to advertise different products and online services without requesting your permission.

Msgstars iPhone Calendar Virus

The purpose of this unwanted app is not to harm your iPhone yet its presence on it could indirectly result in a number of security issues, which is why the advisable course of action if you have Msgstars installed on your device would be to delete this undesirable software.

As we said, this app tends to cause sudden page redirects in the users’ Safari and Chrome browsers in order to boost the traffic of certain websites that need more visits. This form of site-promotion earns money for the creators of Msg Stars Online on the basis of the Pay-Per-View model. This explains why the browser-hijacking app that you currently have on your hands is so irritating and obstructive and why it doesn’t even allow you to limit the frequency of its page redirects.

A big problem with these apps is that their uncontrolled redirects and generation of different types of pop-ups and banners on the users’ screens could potentially lead to some rather unpleasant consequences. It’s possible that you may get exposed to virus apps that would try to damage your device or spy on you if you keep the hijacker on your device for long. This is mainly because not all of the content that applications like Msgstars advertise could be verified as non-harmful. Therefore, if you don’t want to risk getting your iPhone infected by some damaging iOS virus, it’s best to remove Msgstars ASAP. If you are having difficulty finishing the removal process on your own, you are free to use the removal guide you will find within the next lines.

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:

  1. Select the Security icon and then click on “Block pop-up windows“. This should stop many types of pop-ups from appearing.
  1. 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.
