Risbonese iPhone


Risbonese is a type of browser hijacker that is aimed at Apple devices. Risbonese targets the main browser on the infected iPhone or iPad and integrates with it. Thus, Risbonese takes over the browsing program and imposes its own settings.

The Risbonese iPhone Calendar Spam

If this particular application has been detected on your iPhone or other iOS device, then you’ve likely already noticed certain changes during your browsing sessions. For example, you may have started seeing more and more different types of online ads such as popups, box messages and banners. Furthermore, you might have also started experiencing page redirects to various seemingly random web locations that try to sell you something.

Another thing that this app may have down is it could have changed your browser’s homepage and set a new search engine as the default one. And the only way you will be able to restore your Safari, Chrome or other browser settings is if you see to the removal of Risbonese from your portable device. Below we have included a set of instructions to walk you through the removal process, so this shouldn’t be much of an issue for you.

But before you proceed to those steps, we’d just like to put a few more words in regarding Risbonese. As most other hijackers, this application is seen as potentially unwanted. And one of the reasons for this is due to the risk of it exposing users to dangerous and harmful content, including Trojans, ransomware viruses, etc. Therefore, we also recommend abstaining from interacting with any of this program’s ads until it is finally removed.

Note that after you do that, you will no longer get any events automatically added to your Calendar. Instead, theyd go to the email you have provided. This also applies to the spam youve been getting – it would too go to your email, but at least you wont be getting the spam notifications on your screen.

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.
