Kudesa20 “Virus” – what this program really do?

Browser hijackers are a type of software, which is generally specialized in displaying numerous advertisements (pop-ups, banners, new tabs, in-text messages, blinking boxes) directly on the screen of your iPhone, iPad or iPod. The main idea behind this activity is profit generation thanks to aggressive advertising methods like Pay-Per-Click or some sponsored ads positioning. The vendors and advertisers, who use tools like Kudesa20 “Virus”, are mostly interested in receiving clicks on the displayed popping messages. They also tend to monitor the users’ browsing history and use it in their favor, by tailoring the generated ads with the latest users’ web searches. Such activity, though invasive, is not considered as harmful according to the law. However, a problem may occur if the advertisers overdo it with the amounts of ads they display.  This may cause irritation and browsing disturbance to the users, who have ended up with the browser hijacker on their iPhone or other portable smart device. Some people are also concerned by the fact that they are prompted to interact with sketchy ads and sudden page redirects to unknown websites, which may be potential transmitters of security hazards and viruses. That’s why they often refer to programs like Kudesa20 “Virus” as potentially unwanted and seek for ways to remove them. Fortunately, uninstalling a browser hijacker is not that complicated and all you need is to carefully repeat the steps in the removal guide below. If you want to avoid such programs in the future, we recommend you stay away from unknown app developers, research well the apps that you install on your iPhone and stick only to the App Store.

Kudesa20 “Virus” Removal


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.
