Virus is a form of browser-hijacking software that can alter the settings in your browser, thereby making it predisposed to heavy ad-generation. is known for placing a new search engine in the browser and for changing the new-tab and homepage addresses. Virus

The Virus will try to trick you into allowing Push notifications.

The irritation that browser hijackers like bring with their ads, frequent page-redirects to ad-heavy sites, and with the changes they make in the browsers they are installed on could surely make it rather difficult as well as frustrating for the regular user to surf the Internet. This, however, isn’t the only problem with this sort of apps. There is actually a much bigger issue that many users don’t even consider and that is the possibility of getting exposed to much more dangerous forms of malware and viruses due to the hijacker’s presence in the computer. We are talking about threats such as Ransomware, Spyware, Trojans, Worms, and other similar malware programs. The hijacker itself doesn’t really harm the computer – it simply takes over the browser and transforms it into an ad-generating platform. The main goal of most apps of this kind is to promote various products and sites since the owners of said products and sites pay the hijacker’s creators for each user that gets redirected to them. This is also the reason behind the heavy ad-generation you are likely to experience in your browser if is in it. The changes to the starting page, the new-tab page, and the search engine tool are also aimed at getting you to visit various sites that have lots of ads in them and that constantly try to sell you stuff.

The Yellow Label Tokyo Virus

As we said, the irritation caused by apps like Yellow Label Tokyo is actually the lesser of two problems. We consider the main problem with browser hijackers to be the overall lack of quality control with regard to the adverts and the page-redirects that get spammed inside the users’ browsers.

You could never be fully sure if a given hijacker-generated advert isn’t actually a redirect link to some illegal website controlled by hackers and used for the distribution of Ransomware or Trojan Horse viruses. Another unpleasant possibility is getting redirected to a phishing page that tries to obtain your passwords and usernames for other sites or your credit/debit card details. This, however, may also happen if you end up clicking on a misleading advert generated by an app such as All things considered, there really isn’t much point in keeping this unwanted software in your computer. Therefore, our suggestion for you is to explore the guide from down below as soon as you finish reading this post. The steps from the guide will allow you to uninstall the unwanted and also remove all changes that it has imposed in your browser. For further assistance, there is also a powerful removal tool in the guide that has been tested against this sort of unwanted apps.
