Remove virus redirect from Mac

This article is tailor-made for removing virus from Mac so that its malvertising through browser redirects and popups comes to a halt.

No matter how frustrating it sounds, computers with macOS onboard are being shelled with petty, yet hugely noxious threats collectively referred to as adware. Those who find this phrase far-fetched and still unconditionally trust in the long-standing mantra about the opposite should take a look at the Onclickbright threat. It hinges on a prolific strain of adware that sneaks into a Mac through a minimum of user involvement and takes over the default settings in Safari, Google Chrome, and Mozilla Firefox. The upshot of these shenanigans is that the prerogative of deciding which websites to visit suddenly slips out of the victim’s control. The affected browser starts redirecting the web traffic to URL concatenated by a string denoting the campaign ID, which is a shady counterpart of a garden-variety affiliate identifier.

Browser being redirected via

The rerouting often takes place spontaneously, at least that’s what it looks like to the naked eye. Here’s a common scenario: when on a news site or a social network, a user gets rerouted to out of the blue after randomly clicking something. However, there are distinct prerequisites underlying this ostensibly unsystematic drag. In addition to skewing custom settings such as the homepage and default search engine, the potentially unwanted application (PUA) that has previously infiltrated the Mac can invoke scripts that do the evil magic amid a web surfing session. Therefore, the annoying scheme is multi-pronged as it relies on both specific triggers, for instance the victim’s web search attempt, and on inconspicuous execution of dodgy scripts.

What’s the whole point of this foul play? For a security-aware person, it’s as clear as day. Onclickbright is a conduit for what’s called malvertising. This is an unethical way of promoting web services and applications through intrusive techniques. In other words, the browser hijacker is intended to dupe Mac users into opting for a solution they don’t need. When redirected via, the browser resolves a merry-go-round of ad network domains and ultimately lands on a fishy download recommendation page. These resulting sites can vary each time the forwarding occurs. For instance, it can be a page pushing the RadioSearches extension, a browser hijacker that has no information lookup power of its own – instead, it reroutes all queries to Yahoo.

Malicious browser add-on pushed on a landing page related to Onclickbright virus

In this case, the aggressive promo site displays a popup request to show notifications. This adds yet another layer to the brainwashing, because if granted, the privilege allows the add-on to trigger numerous web push notifications even outside the browser. A yet more intricate landing page bolstered by Onclickbright Mac virus is one that recommends installing a booby-trapped Adobe Flash Player update (see screen capture below). It’s parked at The drive-by download is a ZIP file that supposedly contains the update. However, the installer combines the legitimate product with one or several extras such as scareware, adware, or a banking Trojan. The Flash Player related hoax is notoriously prevalent in the Mac malware distribution area.

Onclickbright is also involved in rotating rogue Flash Player updates

As a matter of fact, there are many more PUAs whose propagation is fueled by Onclickbright hijacker. They run the gamut from irksome browser toolbars to malicious bundles that install different types of Mac viruses without the user’s awareness. Several other examples of the apps relying on this distribution cradle are as follows:

  • FunSafeTab;
  • Media-Tab;
  • SocialNewPages;
  • TVPlusNewTab;
  • NewTabTV;
  • ConverterzSearch;
  • SportsHDSearchs;
  • TiktokSearches;
  • StreamsSearch;
  • TechSignalSearch

On numerous occasions, will be bringing the victim to a site that doesn’t endorse any software but pulls off the above-mentioned web push notifications hoax instead. Its URL is It may cloak its tricky requests underneath a human verification checkbox which, once ticked, automatically gives the unwanted service the permissions it wants. This single click becomes a springboard for a deluge of popup ads on the Mac.

While the Onclickbright virus often sets sketchy bundles in motion, it mainly infects Macs in the exact same way itself. Therefore, it’s always a good idea to explore the deep structure of a software package before agreeing to the bulk setup. As soon as the pest is inside, it changes the Internet browsing preferences and establishes persistence by adding a Login Item and possibly also a new configuration profile. These quirks should be taken into consideration as far as Onclickbright removal goes. The paragraphs below will explain how to iron this infection out of a Mac for good.

Onclickbright virus manual removal for Mac

The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.

  1. Expand the Go menu in your Mac’s Finder bar and select Utilities as shown below.

    Go to Utilities

  2. Locate the Activity Monitor icon on the Utilities screen and double-click on it.

    Select the Activity Monitor

  3. In the Activity Monitor app, look for a process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn’t necessarily related to the way the threat is manifesting itself, so you’ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop icon in the upper left-hand corner of the screen.

    Stop malicious process

  4. When a follow-up dialog pops up asking if you are sure you want to quit the troublemaking process, select the Force Quit option.

    Select the Force Quit option

  5. Click on the Go menu icon in the Finder again and select Go to Folder. You can as well use the Command-Shift-G keyboard shortcut.

    Use the Go to Folder feature

  6. Type /Library/LaunchAgents in the folder search dialog and click on the Go button.

    Open /Library/LaunchAgents folder

  7. Examine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.

    As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, and com.msp.agent.plist. If you spot files that don’t belong on the list, go ahead and drag them to the Trash.

    Root-level LaunchAgents folder contents

  8. Use the Go to Folder lookup feature again to navigate to the folder named ~/Library/Application Support (note the tilde symbol prepended to the path).

    Open ~/Library/Application Support folder

  9. When the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are Quick Mac Booster, IdeaShared, and ProgressMatch.

    Application Support folder contents

  10. Enter ~/Library/LaunchAgents string (don’t forget to include the tilde character) in the Go to Folder search area.

    Open ~/Library/LaunchAgents directory

  11. The system will display LaunchAgents residing in the current user’s Home directory. Look for dodgy items related to Onclickbright virus (see logic highlighted in subsections above) and drag the suspects to the Trash.

  12. Type /Library/LaunchDaemons in the Go to Folder search field.

    Go to /Library/LaunchDaemons

  13. In the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.pplauncher.plist, com.startup.plist, and com.ExpertModuleSearchDaemon.plist. Delete the sketchy files immediately.

  15. Find the entry for an app that clearly doesn’t belong there and move it to the Trash. If this action requires your admin password for confirmation, go ahead and enter it.

    Drag malicious app to the Trash

  16. Expand the Apple menu and select System Preferences.

    Select System Preferences

    Open System Preferences

  17. Proceed to Users & Groups and click on the Login Items tab.

    The system will display the list of items launched when the computer is starting up. Locate the potentially unwanted app there and click on the “-” (minus) button.

    Delete unwanted login item

  18. Now select Profiles under System Preferences. Look for a malicious item in the left-hand sidebar. Several examples of configuration profiles created by Mac adware include TechSignalSearch, MainSearchPlatform, AdminPrefs, and Chrome Settings. Select the offending entity and click on the minus sign at the bottom to eliminate it.

    Select Profiles under System Preferences
