Qtr-search is a malicious software categorized as a browser hijacker, which means it has the ability to alter the settings of web browsers without the user’s consent. This intrusive software typically infiltrates systems through software bundling or deceptive download links. Once installed, it modifies browser settings such as the default search engine, homepage, and new tab page to promote a specific search engine or website.
Actions and Consequences
Upon infecting a system, Qtr-search starts redirecting web searches through its own search engine or affiliated websites, which often leads to irrelevant search results or sponsored links. This not only disrupts the browsing experience but also exposes users to potentially harmful websites. Additionally, the malware may display excessive pop-up ads, banners, and other forms of online advertisements, further compromising the user’s privacy and system performance.
Moreover, Qtr-search may track users’ browsing activities, such as search queries, visited websites, IP addresses, and geolocation data, to gather valuable information for targeted advertising or other malicious purposes. This invasion of privacy poses a significant security risk and can result in identity theft, financial losses, or other serious consequences.
