MainReady virus removal from Mac

Find out how to remove MainReady, a strain of Mac adware that redirects victims to junk websites, displays annoying ads, and furtively downloads other threats.

There is no such thing as an invulnerable Mac whose built-in defenses stop malware attacks in their tracks. A polemic is underway whether viruses, self-replicating forms of malicious code, contaminate these computers without any user involvement, but the big picture is much clearer when it comes to adware. Often collectively called potentially unwanted applications (PUAs), these culprits are nearly ubiquitous and growingly common in the macOS environment. The tactics employed by the cybercriminals behind a new Mac threat called MainReady demonstrate how treacherous and evasive the present-day adware has become. First things first, it is part of a large malware family sharing several easy-to-identify hallmarks. Similarly to pests called IdeaShared, FocusProvide, PhaseSearch and numerous previously released clones, the dodgy app in question uses an icon with a magnifying glass symbol in it. The icon color can vary, though – from green to bluish. Although this external quirk seems like a trivial feature, it is a red flag to watch out for.

Another thing all the personas of this adware lineage have in common is that they operate in lockstep with notorious, long-running browser redirect viruses. In the case of MainReady, the attack always co-occurs with iterative instances of the victim’s Internet traffic being forwarded to a service called Safe Finder. Although it’s disguised as a fully-featured search provider, this impression is wrong because all the entered queries lead to a Yahoo Hosted Search destination. That’s a custom service that’s, obviously, being mishandled by some wicked makers of Mac viruses who seek easy gain from redistributing the infected users’ traffic. It’s worth emphasizing that before resolving the landing page the browser hits an in-between location related to the so-called framework, another one that’s known to constitute malefactors’ plots.

Ultimately, the MainReady infection forces the victim’s browser to jump from one unwanted site to another in a loop that doesn’t appear to have any apparent hole to escape. The reason is that the original web navigations preferences defined by the user get an overhaul without permission and it’s the adware under scrutiny to blame for these tweaks. Additionally, the harmful app displays sponsored content above the fold to add one more ply to its authors’ monetization hoax. The ads come in various forms and shapes, from in-text links and price comparison sections deposited where none of these materials belong, to full-page interstitial advertisements that are opened on their own and have to be closed off and on so that the browser continues to function properly.

MainReady is spreading alongside ostensibly harmless software via booby-trapped installation clients touted on questionably safe web portals. Predictably enough, the default install in these scenarios doesn’t mention any adjacent entities being pulled into the Mac simultaneously with the core freeware. The only way to see the entirety of bundled objects and uncheck the fishy ones is to select the custom setup mode. Unfortunately, this is what most people hardly ever do. Once the trespass has been completed, MainReady virus creates a rogue configuration profile listed under System Preferences on the Mac. Its task is to establish persistence and prevent the victim from reverting to the correct search engine and homepage settings in their browser of choice. With that said, this is a stubborn pest that doesn’t succumb to regular removal. The good news is, a little bit of thinking outside the box will help vanquish the PUA.
