Remove redirect virus from Safari, Chrome, Firefox on Mac

The adware oldie called Feed Chunk App has staged a comeback in a large-scale Mac campaign, so here’s how to remove it from an infected system for good.

The genre of browser hijacking continues to dominate the landscape of Mac threats. Not only are the numerous web configuration-twisting threats backed by hefty distribution waves, but they are also becoming more adept at escalating their privileges on infected hosts than they used to be. Feed Chunk App is a classic example of how hybrid and tightly interrelated these PUAs (potentially unwanted applications) can get. Portraying itself as a web search enhancement and a kind of news digest tool, this application does quite the opposite and deteriorates a Mac user’s online experience instead. Once inside, it establishes persistence by creating a spoof device profile that automatically manages the victim’s web navigation activities and hampers regular troubleshooting. Specifically, it replaces the default search engine and homepage in Safari, Google Chrome, or Mozilla Firefox with or sometimes string. Notice the extra “c” letter in the URL that deviates from the spelling of the underlying app’s name.

Feed Chunk App virus promotes the infamous Safe Finder service

The major after-effect of this settings distortion is that the Mac user is unable to run web searches with their preferred provider, nor can the victim get the right start page to be visited when launching the browser of choice. Every instance of redirecting to is certainly a nuisance in itself, but it typically cross-promotes yet another nasty service known as Safe Finder. The latter is a long-running Mac virus whose propagation has been fueled by massive amounts of fraudulent traffic and a plethora of booby-trapped software installers. Here’s how the tandem works: the hijacked browser constantly executes a predefined rerouting process that makes the victim go to first, and from there the navigation path is instantly forwarded to Quite predictably for a junk provider bolstered by adware, the resulting page further thrusts all keyword queries toward custom Yahoo Search pages rather than returning results of its own.

All in all, this tangled scheme pursues a typical traffic redistribution objective with Feed Chunk App virus as its driving force. A really unnerving thing is that the user is pulled into the malicious actors’ dirty game without the slightest shade of consent. To infiltrate a Mac computer, the unwelcome application uses a trick as old as the adware industry itself. It tailgates into the system under a smokescreen of another program, possibly a benign one such as a media player or an Adobe Flash update. In other words, this is a bundling scenario where the perpetrating entity is part of a multi-pronged installation client that deliberately obfuscates the real structure of the package. The user clicks through the installer without a second thought, only to unwittingly approve the setup of several apps instead of a single one that’s clearly manifested.

It’s worth pointing out that the shady “dispatching” site,, may appear in the browser’s status bar only momentarily until the adware operators’ coveted monetization service is resolved. There might be a few extra domains in transit that denote advertising networks. The malefactors use these entities to rake in their profits by trading the intercepted unique traffic. The victims who realize that something is totally wrong with their web surfing preferences and dig a bit deeper will promptly discover the root cause: the dodgy URL turns out to be hard-coded in the search and homepage defaults. These settings cannot be edited via the commonplace logic. That’s because the above-mentioned configuration profile is in effect and its grip applies to the misrepresented settings. In some cases, a new extension called Feed Chunk App is listed among the installed browser add-ons, but again, it’s blocked from all disabling and removal efforts.

Under the circumstances, the virus removal procedure is futile unless the user deletes the device profile as part of the repair. Read the following sections of this article to find out how to overcome the persistence of this virus and revert to normal web browsing. When it comes to avoiding threats like this one further on, the tip of the day is to refrain from downloading and installing apps off of unofficial software hubs. Plus, always explore the full composition of installation clients by deselecting their default, or express, option. Consider discontinuing the setup if there are additional entities under the same harmless-looking hood.
