Mac Adware

Mac OS Pop-up Ads Virus
It is possible for Macs to become infected with malware such as adware, browser hijackers, and unwanted apps. These types of infections are often designed to generate revenue through tactics such as generating web traffic, collecting sales leads, and displaying advertisements and sponsored links in your web browser.

If your Mac becomes infected with malware, you may notice an increase in unwanted pop-up advertisements, the installation of unfamiliar programs, or changes to your browser settings without your consent.

When malware is installed on Mac, common symptoms include:

  • Advertisements appear in places they shouldn’t be.
  • Your web browser’s homepage has mysteriously changed without your permission.
  • Web pages that you typically visit are not displaying properly.
  • Website links redirect to sites different from what you expected.
  • Browser popups appear which recommend fake updates or other software.
  • Unwanted programs are installed without your knowledge.

This guide was written to help Mac users remove viruses and malware from their devices, if your just looking for a way to block or remove advertisements from the sites you visit, then you can use a free browser extension like AdGuard.

How did my Mac get infected with malware?

There are several ways that your Mac can become infected with malware. Some common methods include:

  1. Downloading infected software or files: If you download and install software or files from untrusted sources, your Mac may become infected with malware. Be cautious when downloading files from the internet, and only download from reputable sources.

  2. Visiting infected websites: Malware can be spread through websites that have been compromised by hackers. Avoid visiting suspicious websites or clicking on links from unknown sources.

  3. Email attachments: Malware can be spread through email attachments, especially if you open attachments from unknown senders or emails that look suspicious. Be cautious when opening email attachments, even if they appear to be from a trusted source.

  4. Drive-by downloads: Malware can be installed on your Mac without your knowledge through a process called a “drive-by download.” This can happen when you visit a compromised website or click on a malicious link, and the malware is automatically downloaded and installed on your system.

  5. Social engineering: Hackers may use social engineering tactics to try to trick you into installing malware on your Mac. This can include phishing emails or other types of scams that try to convince you to install malware or divulge personal information.

How to remove viruses and malware from your Mac

This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free.
Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.
To remove all viruses from your Mac, follow these steps:

STEP 1: Remove malicious profiles

Profiles are used by IT admins in businesses to control the behavior of their Macs. These profiles can configure a Mac to do many different things, some of which are not otherwise possible.
When it comes to home users, adware and browser hijackers are using the configuration profile to prevent users from removing malicious programs from the computer. This also prevents the user from changing that behavior in the browser’s settings.

In this first step, we will check your computer to see if any configuration profiles are installed. To do this, follow the below steps:

  1. Open “System Preferences”

    From the Apple menu, select System Preferences.

  2. Search for “Profiles”

    When the System Preferences window opens, search for the Profiles icon.
    Search for Profiles in System Preferences

    If there isn’t a Profiles icon, you don’t have any profiles installed, which is normal and you can continue with the next steps.
  3. Remove the malicious profiles

    If there’s a Profile icon, click on it and select any suspicious profile that you want to remove, and then press the – (minus) button. Click Remove to remove the profile.
