Unexpectedly seeing Yahoo Search redirect on browser’s homepage and new tab window does not mean that computer is already infected with a virus.

For this reason, most freeware makers as well as PUP and Adware developers are utilizing the Yahoo Custom Search whenever they create apps that mean to override homepage on internet browser programs. Obviously, the company itself is unaware that cyber crooks are exploiting the custom search for their own fraudulent deeds. Hence, rest assures that the Yahoo will carry out immediate actions to reprimand bad software developers and might as well block them from using the custom search.
Things that will make you unexpectedly see Yahoo Search redirect on the browser includes:
- Installation of malicious browser extension to Google Chrome, Firefox, or Safari
- Installation of software bundles that causes unwanted browser changes
- Clicking on pop-up links that automatically downloads and execute scripts
- Misleading ads that provides “Allow” or similar buttons, which maliciously changes browser settings
From the given sources above, it is clear that most browser modifications, which causes Yahoo Search redirect is without Yahoo’s influence. Individual applet and software developers are the ones who decide to deliberately redirect the browser to Yahoo Search after program installation. As a matter of fact, other adware creators prefer to redirect the internet software to Google or Bing search. It is just a matter of how they design the app and what it can execute once installed on the browser.
Main reason for getting redirected to Yahoo Search is mainly because these adware creators needs to generate online revenue through search results. Moreover, one thing why adware makers are fond of redirecting homepage and new tabs to Yahoo Search is because they find it easier to modify this custom search to reflect their own advertising scheme.
Therefore, it is clear that it is adware makers prerogative why we are seeing Yahoo Search redirect on homepage and new tab of Google Chrome, Firefox, or Safari. Hence, the integration process calls for user’s intervention whether through software installation, browser extension, or scripts.
So the straightforward response if the overtaking of homepage is really a Yahoo Search redirect virus would be “No”. It is unfair to blame the legitimate Yahoo Search for any unnecessary changes on the browser because it is the carelessness of web users themselves. If only they are cautious in acquiring free programs and is very vigilant to software they are installing, there would be no issue about Yahoo Search redirect virus.
