Get useful insights into the WindowGroup Mac virus issue, including its spreading techniques and removal steps that will help tackle the problem.
There is an ambitious player on the Mac malware arena that seems to be maximizing the attack reach at the time of this writing. These perpetrators have been launching a slew of adware applications into the wild exhibiting a uniform behavioral pattern, which proves that they hail from the same dark web source. WindowGroup is one of these dodgy programs. Similarly to its lookalike called WindowMix, it installs itself without requesting a Mac user’s permission in any clear form. The trespass mainly stems from a rogue software update or an app bundle installed by means of a multi-component setup client promoted on questionably safe download aggregates. Having slithered its way into a system, the adware mutilates the way the victim’s default web browser works. To this end, it silently adds an extension to Safari, Google Chrome, or Mozilla Firefox, which automatically seizes permissions broad enough to impact the admin’s web surfing activities.
Perhaps the most distinct evidence of WindowGroup’s shenanigans on a Mac comes down to ads that start appearing all over the pages that the user opens in a browser. At first blush, these items look like run-of-the-mill coupons, popup adverts, comparison shopping objects, and banners that are so widespread on the Internet these days. However, none of them would be displayed on the exact same site as long as the computer is unaffected by the virus under scrutiny. Otherwise, the victim has to dig through piles of this ecommerce junk labeled Ads by WindowGroup and click numerous X buttons on them just to see the original web page content. That’s a major stumbling block thwarting normal browsing. One more concern is that the sponsored information matches the user’s interests quite accurately. It means that the core application has access to the web history and searches done on the plagued machine. This data is supposed to stay private, but the adware makers don’t seem to care.
As if the ad-injection frenzy weren’t enough to make the victim feel fed up with the attack, the WindowGroup virus additionally gets its ugly claws out by changing the user-defined Internet preferences. These include the homepage, new tab, and default search engine settings. The electronic parasite may replace all of these values with a bogus search provider’s URL. As a result, the user’s normal web traffic will be repeatedly redirected to a search engine copycat that reroutes all queries to another service instead of returning its own results. Although the resulting site is legit – it tends to be either Bing or Yahoo – the redirect path ‘touches’ a few advertising networks in transit. It’s the involvement of these in-between domains that allows the crooks to monetize the browser hijack to the fullest.
The techniques to avoid the WindowGroup virus can be deduced from its propagation mechanisms. Just like most Mac infections that focus on exploiting a host’s browsing environment, this strain is doing the rounds as part of applications packages ostensibly offered as one benign program. These bundle installers are all over the Internet, and they aren’t necessarily malicious. What makes them sketchy is the inclusion of potentially unwanted entities into the nice-looking wrapping. The next time you come across a freeware download offer that seems too good to be true, be sure to select the custom install option and explore the wizard for extra items you don’t want.
In case WindowGroup has already entered a system, the reasonable reaction is to get rid of it. There is a hurdle with that. When trying to drag the WindowGroup.app entry from the Mac’s Application folder to the Trash, the infected users get a popup dialog that asks them to enter their username and password. This could be a trick aiming to steal the victim’s administrative credentials, therefore this route is not recommended. Instead, follow a tried-and-tested adware removal procedure below to make the WindowGroup virus vanish without a trace.
