What is ProfessionalHelper Mac virus?

ProfessionalHelper is a type of malicious software that inserts ads and steals sensitive information from Mac users

ProfessionalHelperProfessionalHelper is a malicious application design for Mac operating systems

Mac is a type of machine that has been growing in popularity recently, which also, unfortunately, means that it attracts the attention of various cybercriminals. ProfessionalHelper is one of the newer versions of the Adload malware family that has shown up in the wild a few years ago and continues its malicious spree to this day. While it can be attributed to the potentially unwanted software or adware category, it also possesses plenty of malicious traits that would classify it as a Trojan or malware.

Distributed via fake Flash Player installers or pirated software bundles downloaded from illegal websites, the ProfessionalHelper virus manages to slip into users' devices unnoticed. In other words, nobody installs this app intentionally, as it does not have any beneficial features that somebody might find useful.

If you have found an icon with a magnifying glass on your browser or system, it means it is infected and needs to be cleaned properly. Below we will provide extensive instructions on how to achieve that, as well as a few tips that would help you avoid similar infections in the future.

The effective distribution

In order to be installed on a Mac, a user needs to enter their credentials into a pop-up which shows up every time an app from unsolicited sources is downloaded. So why would users allow this malicious software to enter their systems seemingly deliberately? The answer to this question is that they are tricked into doing so, as they don't know that the installation permission they are granting is for the ProfessionalHelper virus.

In most cases, people are deceived by either facing fake Flash Player installers they believe are required to play multimedia on various websites or when attempting to install illegal software.

If you ever encounter a prompt that asks you to install or update Flash Player, keep in mind that Adobe, the developer of the plugin has discontinued it,[1] as the app is outdated and full of vulnerabilities.[2] Flash has been long replaced by more modern technologies such as HTML 5,[3] which are built-in in any modern web browser. Thus, if you see a request to install Flash Player, completely disregard it, as you will likely be installing malware on your system.

And, of course, we recommend you stay away from all the illegal software installers, as it is one of the easiest ways to infect your device. The method is effective because users believe that they are installing the pirated application, while in reality, they might implement a secondary app in the process.

What does ProfessionalHelper do?

Once the permission to be installed is granted, ProfessionalHelper immediately uses AppleScript to bypass the built-in protection measures such as Xprotect and Gatekeeper, securing its operation without any issues. The virus also creates new profiles and login items in order to prevent users from effectively removing it from the system.

The visible changes include the installation of an extension that becomes attached to Safari, Google Chrome, or another web browser. With the help of this component, malware is capable of changing the homepage and new tab address and also redirecting all the searches to alternative providers, such as Yahoo or Safe Finder.

The results generated this way might not be accurate, and promotions of phishing links might also occur. Those infected can also experience an unprecedented amount of pop-ups, redirects, and other types of intrusive ads.

Typically, when users try to eliminate the extension, they are unable to because it is simply grayed out. What makes matters worse is that the app is capable of harvesting personal user information, such as passwords and other data. This can undoubtedly damage users' personal safety and result in a personal information disclosure to cybercriminals, as well as identity fraud.

ProfessionalHelper removal

When you install a new app on your system, you can remove it easily by placing it into Trash. With the help of mentioned persistence mechanisms, this course of action is not a solution because the app fails to uninstall or can simply reappear in a short while.

Thus, the most effective way to remove the virus is by performing a full system scan with anti-malware software, such as SpyHunter 5Combo Cleaner or Malwarebytes. You can also employ a manual guide to try to delete all virus files; cleaning the web browser is advised regardless of which removal method you choose.

If the virus is running a background process, you might not be able to remove the app in a regular way. Thus, before you do so, you should open the Activity Monitor and shut down the one that might belong to malware:

  • Open Applications folder
  • Select Utilities
  • Double-click Activity Monitor
  • Here, look for suspicious processes and use the Force Quit command to shut them down
  • Go back to the Applications folder
  • Find the malicious entry and place it in Trash.

Login items ensure that the app starts as soon as the computer boots, and Profiles are used to manage various account settings. Thus, get rid of malware-created items as follows:

  • Go to Preferences and pick Accounts
  • Click Login items and delete everything suspicious
  • Next, pick System Preferences > Users & Groups
  • Find Profiles and remove unwanted profiles from the list.

Leftover files are known as PLIST hold various important configuration settings and might hold a virtual role in malware's operation. Remove them as follows:

  • Select Go > Go to Folder.
  • Enter /Library/Application Support and click Go or press Enter.
  • In the Application Support folder, look for any dubious entries and then delete them.
  • Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and delete all the related .plist files.Uninstall from Mac 2

How to prevent from getting adware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
