Adware isn’t limited to computers. Despite what you may have heard, adware is one of the greatest risks to Macs.

Adware is a form of PUP (potentially unwanted software) that can infect your Mac and cause it to show annoying ads within your browser or reroute you to malicious sites. The number of macOS malware variants continues to rise, with AV-TEST data revealing 673,676 new variations were produced in 2020, up from 58,193 in 2019.

How Is Adware Harmful?

Adware is harmful software that displays advertisements or new windows whenever you use your web browser. Its primary function is to earn click-through money for its creator, but it could also have more malicious goals, such as stealing your personal or financial data.

The most typical way for adware to infect a Mac is through third-party software that is not obtained through the official Apple App Store. For instance, it has been revealed that the people behind the Shlayer trojan (which is commonly used to install adware) are willing to pay website owners, YouTubers, and maybe even Wikipedia editors to steer traffic to their dangerous downloads. Adware could be created by some programmers and used to infect otherwise safe software.

Adware is dangerous and intrusive regardless of where it originates. Pop-ups and unanticipated reroutes are only two examples of the ways in which this might make your online experience less than ideal. On the other hand, it can collect your data and then sell it to third parties, many of whom will not have your best interests at heart.

Adware Indications You Might Look Out For On a Mac

A few telltale symptoms indicate adware may have infiltrated your Mac. It would be best if you didn’t think that you need to view all of these simultaneously to conclude that your device is infected with adware because they can arrive separately.

  • Adware can cause a slew of unwanted pop-ups to appear at once. Moreover, it could make adverts and windows appear one after another or more often than usual. In some cases, these prompts may show up in unexpected locations.
  • There may be an increase in the number of advertising displayed if adware has infiltrated your Mac. These may be placed anywhere on a website, including banners, search results, and in the body of text.
  • You may be taken to unfamiliar websites if you click on a link that contains adware. You should expect to see questionable adverts or deals on these sites.
  • If adware infects your Mac, it might alter your homepage.
  • Adware may install additional browser components, such as toolbars and extensions. None of these will be tools you’ve added yourself, and clicking on them could result in installing additional malware.
  • If you notice a significant slowdown in the performance of your Mac and/or web browser, you may have an adware infection. The same is true if you’ve noticed an increase in browser or Mac crashes.
  • Pay attention to any automatic installations of software since these could be further instances of adware or malware.
  • Mac adware may cause slow performance, but your computer is almost certainly infected if you also experience the other symptoms on this list.

Adware Removal Instructions for Mac Computers

Although removing browser adware will enhance your browsing experience, it won’t necessarily protect your Mac from virus infection. Hence, it is a must to remove adware from Mac immediately.

Adware is a type of software that is loaded on your Mac at the same time as genuine software. Adware can only be removed by going through every file on your system and eradicating it. This can be done by hand or with an adware removal tool.

To delete files manually, you can just move them to the Trash. The annoying adware may remain on your Mac even after you empty the Trash because of leftover related files buried deep within system folders. On the other hand, adware cleaners are an automated choice that performs a comprehensive system scan and gets rid of all dangers they find.

Avoiding Adware Infections

  • Check out who made the app first on Google and get it directly from them.
  • Stay away from the bundle installs (offers bundled with the primary software).
  • Get a jump on things by reading some third-party program evaluations.
  • Invest in a Mac antivirus program with real-time protection.
  • Avoid opening attachments in emails unless absolutely necessary.
  • Don’t rely on banners to get what you need; instead, do a Google search.


In many browsers, adware is an undesirable and unwanted intruder. It attempts to deceive or coerce you into clicking over to a website you had no intention of visiting to generate income for the corporation that generated it. Some versions of the advertising software also have viruses buried within them, which poses a significant threat to both your Mac and the information it stores.

If adware is allowed to go unnoticed, it poses a real risk, but if sufficient knowledge is gained and the appropriate tools are utilized, it is simple to manage. You can easily eliminate adware by avoiding dubious or too-good-to-be-true links and employing a reliable adware removal application.

In the event that you make a mistake and allow the adware to enter your system, you should keep in mind that the intrusive adverts you experience are just the tip of the iceberg. These strains capture personally identifying data like your location, IP address, and browser history, which is another component of the problem that cannot be seen with the naked eye. You can stop anyone from acquiring this information if you use a dependable virtual private network (VPN) on your Mac. It cloaks your Internet Protocol address and your actual location and encrypts your web traffic from beginning to end.
