Yahoo Tab Search adware is a type of potentially unwanted program (PUP) that affects computers and web browsers. It is designed to modify the default search engine and homepage settings of popular browsers such as Google Chrome, Mozilla Firefox, and Internet Explorer, replacing them with Yahoo Tab Search. Once installed, this adware displays intrusive advertisements, redirects users to sponsored websites, and collects browsing-related data for targeted advertising purposes.
Yahoo Tab Search adware can infect computers and browsers through various methods. It is often bundled with freeware or shareware programs that users download from untrustworthy sources. When users install these programs without carefully reviewing the installation process, they inadvertently allow the adware to be installed as well. Additionally, users may encounter this adware while visiting malicious websites or clicking on malicious advertisements. Once installed, Yahoo Tab Search adware modifies browser settings without user consent, making it difficult to remove and restoring the previous settings can be a time-consuming task.
