How to remove MetroPremium 1.0 app virus from Mac


With the MetroPremium Mac adware wave gearing up for a rise, it’s important to know how the unwanted app affects computers and how to remove it for good.

A new highly prolific adware family is shaping up to be a serious player on the Mac cybercrime arena. The ambitious operators of this campaign have been releasing several PUAs (potentially unwanted applications) at a time since mid-October 2019. More disconcertingly, there is a clear upward trend in the wicked developers’ productivity. Obviously, there has to be a motivation behind such a boom. What is it? To get the big picture, let’s take a close look at the app called MetroPremium (also referred to as MetroPremium.app or Metro Premium), one of the recent spinoffs of this growing lineage. Putting the unique name aside, it is a clone of a series of Mac adware samples discovered in the past couple of weeks, including DefaultProducts and IdeaShared. The evident common denominator across these app instances is that they all have a version number of 1.0 indicated next to their names in the infected Mac’s Applications folder. Another shared feature is the round green icon featuring an image of a magnifying glass inside.

In terms of the claimed functionality, MetroPremium 1.0 takes after all of its replicas as well. The respective browser extension is supposedly intended to improve the way the user looks up information on the Internet by reducing search times and delivering refined results via proprietary algorithms. This feature set turns out to be a dummy, though. Instead of introducing online experience enhancements, the adware imposes changes of personalized settings in Safari, Chrome, and Firefox on the plagued Mac. The worst part of this tampering is that the modifications are made without the victim’s approval or even awareness. This way, MetroPremium redirects a major portion of the web traffic to junk search engines, with the process of this hijack involving intermediary ad networks that aren’t discernibly resolved in the browser but, technically, still receive hits from the contaminated computers.

Unsolicited forwarding of one’s web browser to worthless search engines with ads above the fold isn’t the most disturbing symptom of MetroPremium 1.0 virus activity. A much more obnoxious effect is that the victim will be occasionally rerouted to sites hosting aggressive popup alerts. These landing pages can be anything from tech support scams to pesky hoaxes that push rogue system utilities under the guise of “must-have” cleaners. The scare theme is usually fueled by fake Mac virus detection reports or messages about critical privacy risks. Essentially, this is an extra layer of attack monetization aiming to cross-promote affiliated malicious software. Furthermore, these warning notifications are problematic to get out of the way by simply closing the browser tabs. In many cases, the only way to get rid of them is to force quit and restart the browser, which makes the predicament yet more annoying.

Ads by MetroPremium are additional elements of this nasty campaign. They come in the form of in-text links, comparison shopping areas, banners showcasing coupons and freebies, as well as interstitial adverts popping up beyond the current browser window. Not only do these items slow down the affected web browser to a crawl when a certain amount of them is reached, but they also keep the users from enjoying their favorite sites as large parts of the page layout end up being overcast by redundant ecommerce content.

On a side note, there are several adware programs hailing from the exact same source and making the rounds concurrently with MetroPremium 1.0. Again, these dodgy apps are strikingly similar on the outside and act in basically the same way. They may even replace each other on an already-infected Mac, displaying a popup that says “Installation Complete” every time this happens. The simultaneous circulation of multiple PUAs representing the same genealogy is a hallmark sign of this particular Mac malware wave. Here is a quick overview of the MetroPremium app look-alikes in question:

LookupShare

LookupShare, also manifesting itself as LookupShare.app, is a piece of adware that installs itself onto a Mac without the user’s permission and alters custom settings in Safari, Chrome, or Firefox. It causes a number of adverse effects that diminish the user experience and impact the performance of the default web browser. In particular, LookupShare substitutes the user’s preferred search engine setting with Bing, Yahoo, or fake search service backed by low-quality advertising networks. The infection tends to additionally display unwanted ads on regular websites that include no sponsored materials if visited from a healthy computer.

In order to serve targeted ads, LookupShare collects PII (personally identifiable information) as the victim is surfing the web. These details include browsing history, bookmarked sites, and quite possibly, even usernames and passwords for online accounts. The privacy issues caused by this adware, combined with a defiant interference with normal Internet navigation, are the reasons substantial enough to get rid of the threat without delay.
