Remove Guroshied virus popup from Mac

Staying away from is definitely a good idea because it is a harbor for popup scams, clickbait schemes, and sneaky Mac malware.

What is the popup virus?

Malware campaigns deployed in the macOS ecosystem are rarely as straightforward as hacking computers or injecting dangerous code behind one’s back. These plots are increasingly hybrid as they combine social engineering and virus distribution under the umbrella of a multi-step attack chain. The Guroshied hoax is an epitome of this tactic. At the initial stage of the manipulation, Mac users are lured into visiting, a site that displays interactive messages whose real purpose is a far cry from what they say. Once on the hook, the unsuspecting person runs the risk of granting redundant permissions to the shady service. This, in turn, becomes a catalyst for manifold exploitation that runs the gamut from clickbait trickery to outright infestation of the host system with malicious applications.

Those who exercise proper online hygiene may argue that visiting such a fraudulent web page is at odds with basic vigilance. True, but when a user goes there, it’s not because they have literally typed the domain name in a browser plus a super-long concatenated string with a bunch of identifiers that denote a specific sub-campaign of the multifunctional ruse. Instead, people mostly end up on after clicking some eye-catching ad on a popular site. Cybercriminals are very adept at gaming the rules of legitimate services to put their dodgy stuff on them and thereby give their attack surface a boost. One more plausible scenario relies on browser hijackers previously deposited on Macs. These electronic culprits are notoriously effective in terms of tweaking victims’ web browsing preferences to organize the web traffic to their advantage.

Putting aside the specific mechanism that brought a user to, the subsequent series of events is a nuisance. There are several landing page designs in the scammers’ repertoire. The most common variant mimics garden-variety human verification that’s supposedly required to access some useful content. At this point, a major giveaway can be noticed with the naked eye. To confirm that you are not a robot, you are instructed to click an “Allow” button on a popup that says “ wants to show notifications”. These are completely different things, aren’t they? One way or another, the user is one click away from letting classic malvertising activity commence on their Mac. It mishandles web push notifications, a feature used by websites to keep their audiences abreast of new materials they publish. allowed to show notifications in Chrome

Threat actors have learned to weaponize this technology to deliver sketchy content to users. It turns into a springboard for generating pop-ups that originate from a reconfigured web browser. The worst part is that these ads are also displayed outside the browser. For instance, they will be inundating the top right part of the Mac’s desktop, making the victim close an insane number of these pop-ups to see their normal icons and widgets. Another nontrivial risk stems from the contents of these notifications. Most of them contain links that lead to junk sources such as gambling sites or tech support scams. Some will even claim that a virus has been detected on the computer. An example of such imaginary peril is Trojan_%$@!F, which is purportedly capable of erasing the operating system.

A rule of thumb when dealing with Guroshied virus pop-ups is to avoid clicking them and to ignore what they say because all of it is a lie. However, this is cold comfort for users who will keep getting those annoying notifications regardless. To address this problem for good, you’ll need to fix the browser settings and make sure that the fraud is not backed by malware that might have triggered the brainwashing scheme in the first place. In the screenshot above, you can see and several spin-offs (ones with six-character strings prepending the URL) abusing Google Chrome’s security and privacy configuration. Notice the “Allowed notifications” tag for each. Resetting these permissions is a good place to start, but it’s half the battle. Use the following recommendations to get rid of Guroshied pop-ups completely. Going forward, be sure to take human verification alerts on unfamiliar web pages with a grain of salt.

    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.

  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.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 com.AuraSearchDaemon, ProgressSite, and IdeaShared.

    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 popup 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.

    LaunchDaemons folder contents

  14. Click on the Go menu icon in your Mac’s Finder and select Applications on the list.

  15. Find the 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.

    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 Safari Preferences. Select the offending entity and click on the minus sign at the bottom to eliminate it.
