The end goal of this undesirable software is simple: it is an app programmed to make money through aggressive online marketing with little to no regard for the user’s safety or undisturbed browsing experience. In fact, apps like tBrains are specifically designed to be as obstructive and intrusive as possible as this will typically force users to interact with the promotional content that they generate which, in turn, is what earns revenue for their creators on the basis of models such as Pay-Per-View and Pay-Per-Click. The browser-hijacking app like tBrains, GsecurecontentSearch Marquis or Search Baron is also likely to tamper with the homepage and toolbar settings of the browser, taking over them and forcing them to spam you with different forms of online advertisements, including pop-up messages, misleading links, questionable download buttons and security warnings, clickbait banners, and even fake download requests.

tBrains for Mac

tBrains for Mac is an example of a newly-released browser-hijacking tool that can get installed on pretty much any browser, causing uncontrolled page redirects in it. The redirects spammed by tBrains for Mac could potentially lead to questionable sites so its best to not trust them.

Here, it’s worth mentioning that the developers of such software don’t normally seek to harm your computer or to expose it to any sort of harm. It’s just that they are indiscriminate with regard to what content and sites their hijackers promote as long as it earns them money. Needless to say, this means that many of the web addresses that get promoted by such software could potentially be hazardous. This, combined with the fact that you virtually have no control over the ads and redirects spammed by the hijacker, means that the chances of having your Mac exposed to ransomware, Trojans, or other dangerous viruses are quite high if there is a hijacker added to any of your browsers.

What is tBrains?

tBrains is an aggressive site-promoting software component that can only work when attached to your browser. Typical symptoms associated with tBrains are unwelcome changes in the browser’s settings and sudden redirects to websites you have never intended to visit.

If you have recently noticed any of this inside your browser, be sure to further investigate the issue and if it turns out that a hijacker such as this one is causing them, uninstall the unwanted app ASAP.

The tBrains app

The tBrains app is a software tool for unwanted ad-generation that hijacks the search engine of the browser and floods it with sponsored search results. The tBrains app is typically delivered into the computer with the help of another app that serves as a disguise.

That is why it is essential to never download new software that doesn’t seem trustworthy and reliable. Not only will that keep hijackers like tBrains away from your Mac but it will also help you protect your machine against more serious threats like phishing viruses, Trojans, or ransomware.
