Did you know that a lot of Android apps might actually have a hidden element that might impose changes on your browsing app and/or conduct irritating ads-generation on your display? In case the starting page and/or the default search engine of your Chrome, Firefox or of any other browsing app you might be using has been replaced and if you are frequently getting nagged by intrusive banners, pop-ups and browse page-redirects, then you are likely dealing with some sort of app that contains a browser hijacker in it. A browser hijacker is a software element that runs processes such as generation of adverts and that is likely to try to make changes to the user’s browser in order to conduct its aggressive advertising campaigns. “Test hello world” is a recently detected example of such a software piece – many customers have complained about it and here, we will tell you more about this pesky hijacker.
The first important thing to note about “Test hello world” and other similar software components is that they are not typically supposed to cause any harm – they aren’t viruses like Ransomware or Trojans and their primary task normally revolves around advertising. However, due to the intrusive and aggravating nature of the advertising processes conducted by such apps, most customers find them obnoxious and unwanted and sometimes even refer to them as malware viruses (although they are technically not that).
Setting aside the changes to your browser ad the intrusiveness coming from the ads, there’s one more serious problem that might come from a hijacker app and that is the potential for your Android smartphone or tablet getting exposed to some nasty piece of malware like a Trojan Horse, a Worm, a Ransomware virus or some other similar threat. This could potentially happen if you aren’t careful and tap on any of the ads that “Test hello world” might put on your screen. Though most of its promotional materials should be safe, you can never be fully certain that some of the ads isn’t actually a redirect to some dangerous web location used for malware distribution.
That is also why we advise you to use the guide below in order to uninstall and remove “Test hello world” and also make sure to be careful with what sources for new apps you use in future. Generally, using only the Play Store and always conducting a quick research on new applications you want to download is what you should do if you want to keep your Android device safe.
“Test hello world” Removal
Whether you use the default “Internet” App for browsing or a different browser like Chrome you need to go to:
Locate the Browser/App in question and tap on it.
Now the method is effectively the same for users using both “Internet” and Chrome/Other Browsers, yet for more clarity we have provided instructions for both:
For “Internet” Browser Users:
Tap the Force Stop button.
Now tap the Clear Data and Clear Cache Buttons.
For Google Chrome Users:
Click on Force Stop.
Then click on Clear Data and Clear Cache.
Restart your Browser. It might be a good idea to Reboot your Android device, just in case.
If you are still seeing Ads in your browser, it is likely they are generated by the websites you visit and there is nothing you can do about it.
However, if you are seeing Adverts outside of your internet browser, then one of your installed Apps contains the problematic Adware. In this case you need to take a look at this guide.
