Apple Macs have a well-deserved reputation for being secure, but no computer is ever 100% safe from malware. That’s why threats like the NBP Mac virus exist, and you need to be aware of them.

What does the NBP virus do?

The NBP virus, also known as nbp.app, is part of the Pirrit family of malware. It’s a form of adware and browser hijacker. If your Mac is infected with the NBP virus, you may experience a few different symptoms:

  • Your web browser is automatically redirected to sites you didn’t choose.
  • Your home page is wrong, and you can’t reset it to its default.
  • You see a lot of particularly intrusive ads, including pop-ups.
  • You find suspicious programs or browser extensions installed on your Mac.

As well as these more visible symptoms, nbp.app may be engaged in malicious activity in the background. This malware could possibly be gathering your personal, private information, including your browsing history, usernames, passwords, credit card numbers, contacts, and more—all of which can be sent to cybercriminals.

 

These hackers can then either use this information to target you for further attacks, or they may sell your data to other cybercriminals who perform those attacks instead. If they find anything embarrassing or financially sensitive, like unreleased corporate plans, they may blackmail you by threatening to share it publicly.

 

Another common motivation behind this malware is to serve you aggressive advertising. That may include scareware, a form of advertising that involves scaring you into downloading an app on your Mac. For example, you might see a pop-up that says you have a virus on your Mac, and that you need to install a particular app right now to get rid of it.

 

As you can see, whether it’s to steal your data or serve you ads, malware like the NBP virus is usually driven by money. In some cases, this malware may actually direct you to legitimate goods and services, because even then, the criminals will make money through affiliate advertising.

How does the NBP virus infect Mac?

Nbp.app is a form of adware that affects Macs. It can potentially take control of your web browser, targeting you with intrusive ads, stealing your valuable personal data, and automatically redirecting you to suspicious web pages. It may install other malware too.

What is the “NBP will damage your computer” notification?

If you see “NBP will damage your computer” on your Mac, it may be macOS warning you about this malware. Or it could be a fake message created by nbp.app.

How to manually delete the NBP virus from MacBook

The NBP Mac virus can be annoying, so you should deal with it quickly. If you choose to do it manually, you’ll need to take a few key steps:

  1. Quit any dangerous apps or processes
  2. Delete suspicious apps
  3. Remove unwanted login items
  4. Get rid of suspicious user profiles
  5. Delete any suspicious web browser extensions

1. Delete files and folders associated with NBP malware

Like a lot of malware, the NBP virus will often leave files and folders in typical places on your system. You can go through a manual process to delete these from macOS, and that may be enough to give you back control of your Mac.

1.1 Quit any dangerous apps or processes

Before removing anything from your Mac, you need to make sure there are no suspicious apps currently running. This may also include processes running in the background, which may be linked to the NBP virus on Mac. Follow these steps to use Activity Monitor to view and quit running processes:

  1. Press Cmd+Space to bring up Spotlight. Search for and open Activity Monitor.
  2. In the % CPU tab, look for anything that could be related to the NBP virus. It may be using a lot of CPU.
  3. To quit a process, double-click it, click the Quit button.
  4. Select Force Quit. Do the same with anything else suspicious that you find in Activity Monitor.
Before deleting anything from your Mac, use Activity Monitor to quit any processes that may be connected to the NBP virus.
Step 1. Open Activity Monitor
In your Mac's Activity Monitor app, click on the % CPU tab at the top. Now look through the running processes for anything related to the NBP virus.
Step 2. Check for processes to shut down
In Activity Monitor, double-click a process that you want to stop. This will bring up a new window. Click the Quit button at the bottom.
Step 3. Click the Quit button
Finally, Activity Monitor will ask you to choose Quit, Force Quit or Cancel. To make sure the process is completely stopped, click Force Quit.
Step 4. Select the Force Quit option

1.2 Delete suspicious apps

The NBP virus may come bundled with other programs you’ve installed. This scam is often used by unscrupulous app developers looking to make a quick buck. Certain free media players, for example, are known to do this. Here’s what to do:

  1. Check your Applications folder for any suspicious apps—things you didn’t knowingly install or may have added malware to your Mac.
  2. Drag the app or apps to your Trash and empty it.
If there are any suspicious apps in your Applications folder, you should delete them. This may include apps that you've deliberately installed but which come from untrustworthy developers.
Check for suspicious apps

Tip from our experts: 

 

You can avoid many issues by only downloading apps from the App Store or apps that are notarized by Apple. Notarization is a voluntary scheme that lets developers prove their programs are free of malware. Notarized apps, including MacKeeper, are scanned for malware before they ever get to you.

1.3 Remove unwanted login items

A lot of malware will add login items to your Mac. That allows the malware to load up as soon as you start macOS. You can put a stop to that like this:

  1. In Finder, select Go > Go to Folder from the menu bar.
  2. Type ~/Library/LaunchAgents, and hit Enter.
  3. Look for anything related to nbp.app or similar, and delete.
  4. Repeat step 3 with /Library/LaunchDaemons, /Library/LaunchAgents, and /Library/Application Support.

Important: It’s difficult to know what to look for, but users have reported seeing malicious files like myppes.download.plist, installmac.AppRemoval.plis, and com.myppes.net-preferences.plist. If you doubt, search the web for anything you’re unsure about. You’ll often find forums and other sites that discuss the files you’re searching for.

In Finder, go to the menu bar at the top of your Mac's screen, and select Go > Go to Folder. This will bring up a new area for you to type into.
Step 1. Select Go to Folder
Use the Go to Folder function to search for and open the LaunchAgents folder on your Mac. This is filled with apps and processes that launch with macOS.
Step 2. Open the LaunchAgents folder
Looks through the LaunchAgents folder for anything that may be linked to the NBP virus, then delete it from your Mac.
Step 3. Remove launch agents
You should also look in the LaunchDaemons folder and your Application Support folder. These too may hold data related to the NBP virus, which can cause all kinds of issues.
Step 4. Repeat with other key folders

Tip from our team:

 

Rather than manually going through your login item folders, save time with MacKeeper’s Login Items tool. Not only does it find launch agents and launch daemons for you, but it’ll give you information like when the file was added to your Mac. This could be very useful when you’re trying to work out what’s linked to the NBP Mac virus.

1.4 Get rid of suspicious user profiles

In some cases, you may find malware has installed rogue configuration profiles on your Mac. You can remove unwanted profiles like this:

  1. Open System Settings, and select Privacy & Security from the sidebar on the left. Scroll down, and select Profiles under Others.
  2. You won’t normally see anything here, but if you do, it could be malicious. Select the profile and click the minus button.
Sometimes, malware will install rogue configuration profiles on your Mac. You can look for these in your System Settings.
Step 2. Look under Privacy & Security
Hopefully, you won't find any configuration profiles at all in your System Settings, but if you do, you should delete them as soon as possible.
Step 2. Remove configuration profiles here

2. Remove NBP virus from Internet browsers

In addition to installing files and folders on your Mac, the NBP virus can invade your web browser, installing unwanted extensions that cause problems and compromise your privacy.

Keeping your Mac malware-free

Not long ago, it was common to hear people ask: can you get viruses on a Mac? Back then, it was a reasonable question to ask because Mac malware was unheard of. Macs were more of a niche product, with a relatively small audience, so hackers didn’t bother to target them. In contrast, many times more PCs were running Microsoft Windows, making it a bigger target.

 

However, Macs have grown in popularity, and that means cybercriminals no longer see them as a waste of time. The result: you end up with malware like the NBP virus. So don’t be complacent. Follow good cybersecurity practices to protect yourself and your Mac:

  • Never open email attachments from people you don’t know.
  • Avoid clicking on suspicious links on websites, in emails, in messages, or anywhere else.
  • Always check the web address (URL) of the site you’re currently on, to make sure it’s not a fake version.
  • Never click on pop-up ads on websites.
  • Avoid piracy sites, adult sites, and other destinations that may harbor malware.
  • Don’t install software from outside the App Store unless you can trust the developer.
  • Don’t install browser extensions unless you really need them.

Finally, ensure you have a reliable antivirus solution installed on your Mac. While you may be able to manually remove parts of malware installed on your Mac, it’s extremely difficult to find and delete it all. You can save yourself a lot of hassle by using MacKeeper’s Antivirus tool. It’ll do all the hard work for you, tracking down and then deleting malware on your Mac—even if it’s in hidden and hard-to-find folders.
