What is Kosearch.com
Kosearch.com is a browser hijacker, a type of unwanted software that alters web browser settings without the user’s consent. This software typically modifies the default search engine, homepage, and new tab settings, redirecting users to Kosearch.com or associated websites. The primary goal behind such actions is to generate advertising revenue through increased web traffic and the collection of user data. This article delves into the nature of Kosearch.com, its infection mechanisms, redirection behavior, and associated browser extensions. Once installed, Kosearch.com alters browser settings to redirect search queries through its domain. However, it does not provide search results directly; instead, it redirects users through several other websites before landing on legitimate search engines like Yahoo. This redirection process can vary, influenced by factors such as geolocation, and may involve intermediary sites like kosearch.com, myhoroscopepro.com, and favisearch.net. Such redirects not only disrupt the user experience but also pose privacy risks, as each redirect could potentially collect user data. Kosearch.com may come with or promote the installation of browser extensions that further support its hijacking activities. These extensions can enforce the hijacker’s control over browser settings, making it difficult for users to revert changes. They might restrict access to removal-related settings or undo user-made changes to ensure persistence. While specific names of associated extensions are not always mentioned, users should be wary of any unfamiliar or unwanted extensions installed alongside Kosearch.com.
How Kosearch.com infects computer
Kosearch.com can infiltrate computers through several avenues, often employing deceptive tactics to ensure its installation. One common method is “bundling,” where the hijacker is packaged with free software or shareware. Unsuspecting users download and install the bundled software, inadvertently allowing Kosearch.com to take over their browsers. Additionally, it can be distributed via deceptive promotional webpages, freeware and free file-hosting websites, bundled installers, online scams, peer-to-peer (P2P) sharing networks, spam browser notifications, and intrusive ads.
