“Receiver Helper will damage your computer” alert removal

Remove Receiver Helper virus from Mac to remedy the affected web browser and stop obnoxious popups saying that this application will damage your computer.

Hassle-free computing is a misnomer if adware infiltrates a Mac. Whereas some digital threats, such as info-stealers, are covert by design and cause harm without telltale signs of infection, the above-mentioned culprits manifest themselves more than conspicuously. Often referred to as potentially unwanted applications (PUAs), they hit the web browsing side of the Mac by incessantly displaying ads and spoofed popup alerts. Browser redirects that lead to shady or worthless services add a few extra touches to the nasty big picture. All of these unwelcome after-effects of the attack hold true for Receiver Helper, an adware strain that’s currently seeing a sizable spike in distribution. It tiptoes into a system as part of a multi-pronged installer that misleadingly appears to promote a harmless app with no strings attached. Having made it into the Mac, the e-pest shows its true colors by turning the user’s Internet defaults upside down.

Receiver Helper virus is a source of system alerts and browser malfunctions

Receiver Helper virus homes in on the user-defined preferences in Safari, Google Chrome, or Mozilla Firefox. It identifies which browser to target by profiling the victim at the early stage of the attack. This process involves, among other things, a reconnaissance aimed at amassing the details on the hardware set-up, macOS version, third-party software installed, IP address, system language, and geolocation. Obviously, it’s the default browser that undergoes the tweaking. This way, the adware operators make sure that they strike exactly where it hurts. The mechanics of this tampering are as follows: the infection replaces the preferred search engine, start page, and new tab page settings with a page involved in a traffic monetization scheme. It tends to be a search provider copycat that outsources all requests to a real information lookup service like Yahoo or Bing while plugging one or a few in-between domains into the rerouting logic. These transitional URLs are mostly advertising networks that treat all user leads as a tradeable commodity no matter if they originate from legit sources or from unethical browser hijacking techniques.

There is more to a Receiver Helper incursion than the defiant reorganization of the victim’s Internet traffic. It installs a malicious browser extension that meddles with the way web page content is rendered to the user. The misbehaving add-on does this by executing scripts which, in their turn, trigger advertisements based on the browsing history that was previously logged in a stealthy manner. The fact that ads by Receiver Helper are targeted and properly aligned with the infected user’s interests is a heads up in itself. It is a derivative of the privacy encroachment properties manifested by the PUA in question. Simply put, not only is the app a nuisance but it also poses a risk to sensitive data.

It comes as no surprise that macOS Catalina 10.15, the latest iteration of the operating system, flags it as a potential threat. It alerts the users by displaying popups that say, “Receiver Helper will damage your computer”. The dialog also recommends that the suspicious program should be moved to the Trash. There is a hurdle, though: if the victim chooses this shortcut and clicks the embedded button to eradicate the culprit, nothing happens. In some cases, an additional popup will appear and notify the user that the application cannot be removed because it’s in use. Either way, there is zero effect. The system warnings will continue to splash up, making the attack yet more annoying. Under the circumstances, the only tactic that really works is to get rid of Receiver Helper using some of the best practices of Mac malware removal. This will stop unwanted ads, browser redirects, and system errors caused by the intrusive app.
