Query-Whiz adware is a potentially unwanted program (PUP) that infects computers and browsers with the aim of displaying intrusive advertisements. It typically enters a user’s system through software bundling, where it is bundled with freeware or shareware programs that are downloaded from unreliable sources. Once installed, Query-Whiz modifies the browser settings and starts displaying various types of ads, such as pop-ups, banners, and in-text advertisements, on the affected computer.
To infect computers and browsers, Query-Whiz utilizes deceptive techniques. It often disguises itself as a legitimate program or browser extension, tricking users into installing it voluntarily. Moreover, it may exploit vulnerabilities in outdated software or use social engineering techniques to convince users to click on malicious links or download infected files. Once inside the system, Query-Whiz alters the browser settings, such as the default search engine and homepage, to redirect users to sponsored websites and generate revenue through pay-per-click schemes. This intrusive behavior not only disrupts the user’s browsing experience but also poses a potential security risk by exposing them to further malware infections or phishing attempts.
