Chill Tab virus removal from Mac is on numerous users’ to-do list because it changes browser settings without permission and harvests sensitive information.

There are several serious concerns about the behavioral quirks of the Chill Tab Mac app. Contrary to regular software in general and browser add-ons in particular, it ignores such a crucial thing as the user’s approval when making significant changes to the way the web surfing is done. It literally trespasses on a computer behind the victim’s back and then imposes its fishy search provider at tab.chill-tab.com or search.chill-tab.com by tampering with the browsing preferences. In addition to these unsanctioned modifications, Chill Tab engages in a sort of covert reconnaissance on the plagued Mac, collecting potentially fingerprintable information about the user and therefore poses a privacy risk. Another disconcerting fact is that although this app was first flagged malicious more than a year ago, the affiliated pseudo search provider continues to successfully escape blacklisting mechanisms in all popular browsers.

The landing pages that the infected Mac users are forced to visit iteratively look normal and even appear to be professionally tailored. However, both the tab.chill-tab.com and search.chill-tab.com websites are simply appealing wrappings with no real functionality behind them. Whatever you type in the search box, the results will be returned by the Yahoo! custom search engine rather than anything that sounds like Chill Tab. By the way, the linked-to pages are associated with another oldie on the arena of Mac PUAs (potentially unwanted apps) called Safe Finder. So, to recap on this particular subject, Chill Tab claims to enhance one’s online experience but turns out to be a dummy that causes inconveniences and a great deal of irritation to those infected. Obviously, that’s not the way legit software works.

The Chill Tab Mac virus drives traffic to its junk web service by changing the victim’s Internet defaults. It is a cross-browser entity, therefore it supports Safari, Google Chrome, and Mozilla Firefox to an equal extent. The configuration-tweaking routine comes down to altering the homepage, preferred search engine, and new tab page in the targeted browser. The baddie replaces the original values with the fake provider being promoted. By the way, whereas search.chill-tab.com and tab.chill-tab.com are pretty replicas of each other functionally and only differ on the outside (design-wise), the latter has been prevalent during the final quarter of 2018. At the end of the day, the aftermath of this malware attack is that the victims can’t stop being redirected to either nag page when they open their browser of choice, try to do a web search, or trigger a new tab. To top it off, the infection may additionally display bogus browser update alerts in an attempt to trick the user into downloading malicious programs disguised as something benign.

It goes without saying that the app in question doesn’t belong on a Mac. Its authors have no respect for users’ decision-making prerogative and engage in a dirty traffic monetization stratagem. So, continue reading to get a complete Chill Tab virus removal walkthrough.
