What is A Cool Tab

A Cool Tab is a browser hijacker that modifies web browser settings to promote a fake search engine. Upon installation, it typically changes the default search engine, homepage, and new tab URL settings without the user’s consent. This hijacker often redirects search queries to search.cooltabs.xyz, which may further redirect to other dubious search engines. In many cases, A Cool Tab comes bundled with browser extensions that facilitate its ability to control and manipulate browser settings. These extensions are often installed without clear user consent, typically through software bundling or deceptive advertisements. The extensions not only ensure the persistence of the hijacker but also may track browsing activity, potentially compromising user privacy. Due to these intrusive behaviors, it is essential to remove A Cool Tab promptly to restore normal browser function and protect personal data.

How A Cool Tab infects computers

“A Cool Tab” is primarily distributed through deceptive software bundling methods, often hitching a ride with legitimate freeware or shareware applications downloaded from dubious sources. Users typically install the hijacker unknowingly by rushing through installation processes without scrutinizing the terms and conditions or opting for advanced/custom installation settings. Once installed, A Cool Tab modifies browser settings, such as the homepage, default search engine, and new tab URLs, redirecting users to unwanted websites to generate ad revenue. The hijacker can also infiltrate through malicious advertisements, phishing emails, or compromised websites that exploit browser vulnerabilities. Vigilance during software installation and maintaining robust cybersecurity measures are crucial in preventing such infections.
