What does adware on Mac OS do?

Mac adware displays pop-up advertisements, inline-text, and audio advertisements. Adware for Mac is also known to cause browser redirects to suspicious download sites or dangerous technical support web pages, these support web pages pretend to work for Apple Support. In reality, these web pages are scams to deceive users into buying an expensive support contract with false claims. Tech Support web page state your mac is infected with a virus and a service telephone number should be called to remove the virus from your Mac. Read more on tech support scam pages.

Adware is built for revenue, adware serves all sorts of websites by redirecting the browser to a specific ad. Adware is also known to hijack the browsers default homepage and search engine. All the web browser traffic is then redirected using the by adware installed browser hijacker.

MacOS adware is not to be found keylogging, spreading itself throughout your network or infecting system files. Adware is known to collect both personally and non-personally identifiable information (PII) for the Mac and browser. The information collected by adware (not limited to): your IP address, your current location, which is based on the internet providers IP-address, your default installed internet browser, device screen size, Mac system version and even the web-browser history.

All this information is sold for marketing purposes. Some suspicious adware applications have information about how they handle and collect the gathered information in an end user license agreement. However, no one reads the EULA and accepts the EULA by default upon installation.

How to prevent adware on a Mac?

Adware for Mac OS usually installs itself together with other software applications downloaded from the internet. This technique is called bundling and the downloaded software is known as pay per install software. Pay per install software is a monetizing tool for software developers. The software developer gets paid for every new software e.g. adware installation. These pay per install services are abused by many web pages that offer free software. Pay per install software is most likely responsible for the adware infection on a Mac.

The Mac user should be aware of what is downloaded from the internet. Clicking the custom or advanced button during installation can reveal what kind of applications are installed on the Mac during installation. Uncheck any software you do not wish to install.

By paying attention to the installation details during a software installation, the Mac user might prevent the installation of adware or any other potentially unwanted program.

Example of a Pay Per Install Mac OS Adware installer
