This page aims to help you remove Tyy5.xyz “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

It can be really annoying and frustrating if your browser is frequently getting swarmed with promotional messages, advertising links, redirects to pages that you did not attempt to visit and other similar pesky commercial materials. If you are experiencing any of this, then it is also likely that you’ve also recently noticed some unusual changes in your browser. For example, maybe your starting page address has been changed without your agreement or maybe the search engine has been replaced with some unknown custom that you’ve never ever heard about before. If that are the symptoms you are experiencing in your browser, know that you are probably dealing with an app known as Tyy5.xyz. This is a browser hijacker and it can get onto pretty much any browser. In most cases, you can get it on Firefox, Chrome and Edge but it’s also possible to experience the effects of this nagging app on other browsers as well. We understand if you are feeling frustrated and maybe even intimidated by the presence of Tyy5.xyz inside your browser. After all, any software that does something unwanted in your computer should be regarded as a potential threat to your virtual security. Tyy5.xyz, however, is not some Trojan or Ransomware infection and its purpose is not to mess with anything inside your computer system. A hijacker such as this one’s main goal would be to advertise stuff on the users’ screens and to make money out of the ads that it displays. This, of course, means that you will likely be getting a lot of advertisements spammed inside your browser but usually nothing harmful should come from the hijacker. Still, you probably don’t want to keep this nagging app in your PC any longer and for that reason we advise you to have a look at the following removal and uninstallation guide manual.

Some security rules

Despite not being some nasty virus or a malicious program of the Ransomware or of the Trojan Horse category, the presence of Tyy5.xyz inside your computer shouldn’t be taken for something that’s perfectly safe. As you should already know, there are all kinds of misleading, obscure and obscene forms of advertisements all over the Internet and although this hijacker isn’t specifically programmed to show you these exact ads, it might as well do that and the only thing that can really stop it is having the intrusive software fully removed from your computer.

You also need to ensure that you don’t get any more such apps inside your system since it’s always easier to simply prevent the installation of unwanted software than to have to deal with it afterwards. Normally, a hijacker would be added to the installation setup of another program so be careful when installing new software on your computer and always remember to check for bundled components in the advanced setup menu where you can usually find what added apps there may be.
