What Is FocusGuide Mac Adware?
A new adware, called FocusGuide and targeting Macs has been detected in the wild. The adware could be triggering unwanted advertisements, and could also replace your default search engine and new tab page with one of its own. FocusGuide reportedly belongs to a family of adware known as AdLoad.
It is noteworthy that AdLoad is a well-known adware and bundleware loaders family which has been targeting macOS users since 2017, or even earlier. The threat installs a backdoor on the system to drop adware and potentially unwanted applications (PUAs), and also collects information.
Security researchers from SentinelOne recently detected a new campaign distributing an evolved variant of AdLoad. Data shows that at least 150 unique samples of the adware are circling the web this year, some of which successfully bypass Apple’s on-device malware protection known as XProtect.
In other words, AdLoad is a quickly evolving adware family with many iterations in the wild. FocusGuide is just a single example. Other examples include TypicalProcess and ValidBoost. Some of these threats are known to generate error messages, claiming that “[name of adware] will damage your computer.”
If you see such a message associated with FocusGuide, this is a clear indication that you should scan your Mac to make sure it is malware-free. You can learn more technical details about FocusGuide adware from this article, as well as instructions on how to remove it from the system.

FocusGuide Mac Adware – How Did It Get Installed on My Mac?
Several techniques are usually deployed for the distribution of the FocusGuide adware. A significant distribution technique is software bundling. Bundling revolves around programs that pretend to be useful and legit but come bundled with ad-supported apps.
The purpose of bundling is quick monetization. Commonly used software may deliver unwanted apps. This includes media players, file converters, weather toolbars, online streaming apps, etc.
The installers of these programs often present optional offers or free extras. At the same time, they are not designed to appropriately disclose information about added apps. That’s how users fail to notice their presence during the installation of whatever software they wanted to download.
Other scenarios include users interacting with suspicious pages (torrenting and online streaming websites, adult pages, free online games, etc.). On these pages, users may click on suspicious links, banners, and offers. The result may be an unnoticed download and install of a potentially unwanted program.
A very wide-spread propagation is using a fake Flash Player update. Your browser may generate a fake error message, claiming that “Adobe Flash Player Is Out of Date”. Interacting with the message, like clicking on the download button it provides, will surely install an adware on your Mac.
N.B. Once started on your Mac, such a program could access all installed browsers’ settings to apply significant changes. One of these changes often affects the default search engine in your preferred web browser. If your default search engine is altered without your consent, then don’t waste time but go check your macOS security. This problem is a definite sign that a suspicious piece of software has sneaked into your system.
Furthermore, as long as files associated with the FocusGuide adware are running on your Mac, you may be a victim of unsolicited data collection.

Fraudsters may use data records to launch targeted advertising campaigns. Once the data is available on the PUP’s servers, it can be used for the identification of your online interests. Ads delivered by undesired apps may target your interests. At worst, data records will be released on dark web markets for additional revenue.
