Amigatesa is a rogue page-redirecting iOS app that seeks to boost the traffic of certain websites by forcefully redirecting users’ browsers to those sites. Amigatesa can also put obstructive pop-ups on the user’s screen and cause the generation of misleading ads.
In general, if you have such an app attached to your iPhone’s Safari or Chrome browser, you’d likely find it quite difficult to use the device normally as you’d be constantly getting obstructed by its invasive ads, pop-ups, banners, and page redirects. In addition, this app will likely change your browser homepage and/or the default search engine. For most users, this is enough reason to seek to immediately remove the aggressive advertising app from their devices.
Another important reason you should better uninstall Amigatesa, Critical Threat iPhone Message or Risbonese has to do with the potential danger of getting exposed to more harmful forms of malware such as Trojans or Ransomware viruses if the browser-hijacking app is permitted to stay on your device. Unfortunately, lots of browser hijackers like Amigatesa will not really limit the sites they promote only to ones that are safe and reliable. In other words, sometimes, a hijacker like this one may end up redirecting you to hazardous web locations where your device may get exposed to harmful viruses, phishing malware, and other threats that you’d certainly not want to come anywhere near your system.
Because of this, the best advice that we can give those of you with Amigatesa installed on their devices is to remove the intrusive app. We will even help you remove the hijacker by providing you with some uninstallation instructions in the following removal guide.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Aggressive, screen-wide pop-ups, sudden browser redirects, and unwanted changes in your browser/Internet settings.|
|Distribution Method||In most cases, hijackers get distributed via third-party download sources that present them as helpful and cheap apps.|
Remove Amigatesa 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.
This is the first thing you should try if you are getting targeted by this kind of spam.
- Log in yo your account at iCloud.com and tap on Calendar.
- Tap on the Settings icon (a gear icon) located in the lower-left corner of the screen.
- Now, select Preferences and then Advanced.
- Change the Invitations setting from In-app notifications to Email to and provide your current email.
- Lastly, click on Save to confirm the change.
Note that after you do that, you will no longer get any events automatically added to your Calendar. Instead, they’d go to the email you have provided. This also applies to the spam you’ve been getting – it would too go to your email, but at least you won’t be getting the spam notifications on your screen.
The next part of this post will tell you how to check your iPhone for an actual Calendar spam virus and how to deal with such a virus if it gets detected.
To remove Amigatesa Calendar Virus quickly you can try this:
1. Go to Settings on your iPhone/iPad.
2. Open Passwords and Accounts.
3. Then go to Subscribed Calendars.
4. Look for Amigatesa or anything that looks suspicious and delete it.
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.
