Remove ChillTAB Mac virus from Safari, Firefox, Chrome

The post describes the Chill Tab virus issue affecting web browsers on Mac and provides instructions on removing the annoying redirects and popup alerts.

Update: November 2019

People are so concerned about privacy these days and can’t stand any interference with their personal space. This issue has partially migrated to the cyber world as the technology moves forward at a gigantic pace. How about one’s web browsing? This thing is intimate to the bone as it holds tons of personally identifiable information and numerous settings that also speak volumes about the user. The violation of these preferences is just as disconcerting as real-life privacy infringements. That's exactly what happens if the Chill Tab virus takes root on a Mac computer. It doesn’t bother asking for the admin’s approval when changing the most important online surfing defaults.

In particular, the Chill Tab nuisance skews such custom browsing settings as the homepage, search and new tab page in Safari, Google Chrome and Mozilla Firefox on a Mac. In the upshot, the victim finds himself or herself in a wicked loop of constantly visiting the or web page. Although either site is harmless in itself and appears to be some sort of a search provider, it would probably never make it to the user’s browsing history if it weren’t for a sneaky malware attack prior to the emergence of symptoms. This combo of a browser hijacker and persistent adware typically infiltrates Mac machines as part of application bundles. Because the presence of the baddie isn’t clearly disclosed by these installation wizards, people run the risk of unknowingly allowing the setup.

The Chill Tab virus has gained notoriety for its extraordinary persistence and evasion techniques. The affected Mac users find it difficult to spot the associated malicious process in the Activity Monitor, and the unwanted item often hides its footprint from the browser extensions pane as well as the Applications path. It may show up there momentarily when the victim opens either one of these directories, only to mystically vanish right away. Even if found and deleted, which seems to be an instance of great luck, the pest keeps reinstalling itself under a different name to the ‘Users – Shared’ folder. These constant comebacks are a serious hurdle to fixing the problem.

One more pitfall serious enough to make all Chill Tab victims frown is that the virus keeps track of their online activities. Most users are typically clueless about this shade of the threat because it isn’t manifested in the open. It takes a bit of in-depth observation to notice the tip of the privacy infringement iceberg. Both landing pages backed by this infection return Yahoo Search when you enter a keyword or phrase in them, and the results include ads that match your interests based on the recent browsing history. In fact, Chill Tab surreptitiously monitors which sites you visit, what kind of ecommerce information you look for, which Internet services you prefer, and many other fragments of online behavior that should stay private. This is a goldmine of data which, when compiled and thoroughly processed, allows the malware operators to conduct targeted marketing campaigns or even mastermind phishing attacks with a mind-blowing success rate.
In addition to the browser redirect activity that’s certainly noxious, the Chill Tab virus wreaks more havoc by generating popup notifications almost all the time. One of these is a recurrent dialog window recommending the user to install Chill Tab - whatever that should mean, given that the perpetrating program is already there anyway. This popup says, “Are you sure you want to install the extension Chill-Tab?” The culprit must be trying to add another unwanted helper object to Safari via this technique. Hopefully to no avail.

Another symptom is that Safari will be randomly starting up and displaying a popup that says, “Scanning for browser updates”. This will be followed by an onset of another window saying, “Your browser is now up to date!” Next, the user may see the above-mentioned request to install Chill Tab extension. Ultimately, this onslaught turns into an iterative display of nag screens mixed up with browser rerouting. Such a state of things, obviously, isn’t on any Mac user’s wish list, to put it mildly. The Chill Tab ( / virus should be exterminated as soon as possible. The methodology of this cleanup is what the following sections will cover in detail.
