Malware-free macOS is unfortunately turning into a delusion at a steady pace. The good news is it’s not as susceptible to viruses as Windows, but potentially unsafe applications such as adware have been capable of compromising Mac machines for quite a while now. The infection which is the subject of this article is called Trovi, and it’s an extreme nuisance and a big time web surfing experience spoiler. This potentially unwanted code is commonly flagged by antivirus utilities as adware, that is, a program taking advantage of hijacked Internet traffic in order to monetize it and promote certain services. It has been in circulation since 2014 and hasn’t undergone any filtering or blacklisting countermeasures up till the present moment. Seven years after discovery, the malware continues to make new victims who are at their wit’s end trying to get rid of the irritating redirects and bring serenity back into their digital lives.

Trovi homepage

Mac users are ensnared via classic trickery

The Trovi threat is known to be closely affiliated with Conduit, or Conduit Search – one of the prevalent homepage hijackers in the wild. So if you’ve got one on your machine, the other is probably there as well. Just like its Conduit satellite, Trovi is distributed as part of freeware whose spreading pattern in no way presupposes declaring that any sort of bundle is coming along. Scrutinizing the Terms of Service for random free multimedia utilities or browser helper objects might help avoid the contamination but, first off, not necessarily, and secondly, there aren’t a whole lot of users doing that as a rule.

Trojanized Adobe Flash Player updaters dominate the Trovi virus distribution campaign. This hoax is backed by popups that appear on hacked or malicious websites stating that the update is mandatory for proper processing of multimedia content in the browser. Predictably enough, the spoofed installer is a bundle comprising Trovi payload in addition to the harmless core application that supposedly needs fine-tuning. Now that Adobe is dropping support of its long-standing product (the EOL move is due December 31, 2020), cybercrooks are switching to the use of spoofed “Adobe Flash Player Uninstaller” pop-ups to promote the likes of Trovi.

How exactly does Trovi affect a Mac?

This adware changes the web browsing preferences on the infected workstation, namely the values for the homepage and default search engine. The Mac versions of Chrome, Firefox, as well as Safari therefore start to act up, constantly returning or instead of the URLs for the above settings previously configured by the user. There is no actual danger stemming from the landing web page for this adware except for the annoyance aspect. bears a tangible value to its creators, though, because it displays ads to the victims. Whether you click on those banners and sponsored links or not, it’s profitable to Trovi authors. Also, while having no real search functionality in itself, this service redirects all searches to Bing.

When the hijack is underway, can be resolved in the affected browser briefly and isn’t necessarily the actual landing page the victim arrives at. Moreover, it is often one of several “en route” domains the traffic slips through. In many cases, the fraudulently imposed web navigation path additionally encompasses such URLs as and Regardless of the specific series of sites being observed in transit, the Mac user will be hitting in the long run. The role of this reputable search provider is to spice the adware attack with a false sense of legitimacy.

Trovi redirects to Bing

Browser hijacking isn’t the only pitfall

On top of the conspicuous browser redirect activity, the Trovi malware deploys a sort of reconnaissance on the plagued Mac. In particular, it drops tracking cookies and gathers the victim’s sensitive data, such as the browsing history, email address, and details of account logon instances. The architects of this campaign then take advantage of the harvested information themselves or sell it to third parties that may conduct targeted phishing attacks and generate spam. The longer the infection remains on board a computer and active, the higher the likelihood of identity theft.

It’s worth pointing out separately that although you only see the impact of Trovi in the way your web browsers behave, it spreads its cyber tentacles much further than that and drops malicious components into multiple paths in the host Mac. For example, it adds a configuration profile via the command line as part of the attack. The goal of this multi-level compromise tactic is to establish persistence and prevent easy cleanup. That’s why the removal of this adware should be performed in several stages that include resetting the affected web browsers and eliminating the malicious app proper. Below are detailed instructions on what needs to be done.

Trovi 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.

  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.

  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 Trovi, 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 Trovi 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.

  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.

    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
