Happywinners.site is a browser hijacking app that initiates unwanted page redirects in the main Mac browser. Happywinners.site is designed specifically for website promotion and, therefore, it constantly tries to redirect your searches to the sites that it promotes.


Happywinners.site will display pop up ads and messages

Many apps that roam the Internet like Queue Algorithm, Search Marquis are similar to Happywinners.site and all of them try to be installed on as many computers as possible so they can earn more money for their developers with paid site promotions. The general term used for these apps is “browser hijackers”. A major browser hijacker characteristic is that these apps are usually unable to operate alone and need a web browser to attach themselves to in order to perform their activities. Normally, popular Mac browsers such as Safari, Chrome and Firefox are ideal, as they are preferred by a lot of web users. Immediately after the browser hijacker has become part of the system’s main browser users can detect various changes to its settings. Usually, the most obvious ones include a replacement of the default homepage and the main search engine with some new ones, as well as the installation of some new redirect buttons and toolbars that the users have not approved. Such changes make sure that more and more advertising material is constantly being displayed on the screen of the user from the moment they open their browser.

Happywinners.site on Safari

Happywinners.site on Safari is a browser hijacker program and can fill the screen of any Mac browser with aggressive page-redirect prompts, pop-up ads and banners. The best way to stop Happywinners.site on Safari from spamming you is to uninstall it.

A lot of people who seek to set themselves free from the ads invasion can find it difficult to remove the browser hijacker and to make sure it doesn’t come back to any of their Mac browsers. The reason is these apps are designed to remain attached to the browsers for as long as possible so that they can generate pay-per-click and pay-per-view revenue from the ads and the web links they display. Thus, most browser hijackers usually don’t have an uninstall option that users can use in case they decide they want to get rid of them. This is also one of the reasons why many people mistake such applications for dangerous viruses and frequently confuse them with hard-to-remove online threats like Ransomware and Trojans.

What is Happywinners?

Happywinners is an online advertising app designed for promoting websites and displaying advertisements that might be of interest to you. Happywinners is known to force the browser to immediately redirect the user to different advertising pages that generate its creators pay-per-view income.

Not all of the websites that such software may promote, though, are to be trusted. Some of them may contain questionable web offers, low-quality products or unnecessary software that you may be prompted to download or purchase. Not to mention that some of the pop-up ads, banner notifications and redirect links may expose your Mac to subtle web attacks, including transmitters of Trojan horse infections and Ransomware cryptoviruses.
