How to eliminate AccessibleOptimizer adware from your Mac

Also Known As: Ads by AccessibleOptimizer
Type: Mac Virus
Damage level: Medium

What kind of application is AccessibleOptimizer?

While investigating new file submissions to the VirusTotal website, our researchers discovered the AccessibleOptimizer application. After analyzing this piece of software, we learned that it is adware from the AdLoad malware family. Advertising-supported software is designed to run intrusive advertisement campaigns.

AccessibleOptimizer adware

AccessibleOptimizer adware overview

Adware operates by displaying third-party graphical content (e.g., banners, coupons, pop-ups, surveys, overlays, etc.) on various interfaces. Advertisements delivered by this software can endorse online scams, untrustworthy/harmful software, and even malware. Once clicked on, some intrusive ads can execute scripts to perform stealthy downloads/installations.

It is noteworthy that while genuine products or services may be encountered via these adverts – they are unlikely to be endorsed in this manner by any official parties. It is most probable that this promotion is undertaken by scammers who abuse the content's affiliate programs to obtain illegitimate commissions.

Advertising-supported software may need certain conditions to deliver intrusive ad campaigns (e.g., compatible browser/system or user geolocation, visits to specific websites, etc.). However, regardless of whether AccessibleOptimizer displays advertisements – it endangers device and user safety.

It is worth mentioning that AdLoad applications commonly have browser-hijacking abilities, although we did not observe these traits while testing the AccessibleOptimizer adware.

Software within this classification usually possesses data-tracking functionalities, and this might apply to AccessibleOptimizer.

Information of interest may include: visited URLs, viewed pages, searched queries, browser cookies, log-in credentials, personally identifiable details, finance-related data, and so forth. The collected information can be shared with or sold to third-parties (potentially, cyber criminals).

In summary, the presence of software like AccessibleOptimizer on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of adware-type apps; TrustedBrowserValueInterface, and ProductivePlatform are merely a few examples.

Advertising-supported software usually appears legitimate and useful. It can also offer a wide variety of "handy" features, which are rarely operational. Adware typically promises these functionalities as bait to deceive users into downloading/installing.

Remember that even if an app or a browser extension operates as indicated by its promotional material – that is not definitive proof of either legitimacy or safety.

How did AccessibleOptimizer install on my computer?

Adware can be bundled (packed together) with ordinary programs. The threat of inadvertently allowing bundled content into the system is increased by downloading from dubious channels (e.g., freeware and free file-hosting sites, P2P sharing networks, etc.) and by rushing through installations (e.g., ignoring terms, using "Easy/Quick" settings, etc.).

Furthermore, adware is promoted on legitimate-looking download pages and scam websites. Users primarily access these webpages via redirects caused by sites using rogue advertising networks, mistyped URLs, intrusive ads, spam browser notifications, or installed adware (with browser force-opening abilities).

Intrusive advertisements proliferate advertising-supported software as well. Once clicked on, some of the adverts can execute scripts to perform stealthy downloads/installations.

How to avoid installation of adware?

We strongly advise researching software and downloading it only from official/verified sources. When installing, it is crucial to read terms, study possible options, use the "Custom/Advanced" settings, and opt out of all supplements (e.g., apps, extensions, tools, etc.).

Another recommendation is to be careful while browsing since fraudulent and malicious online content typically appears legitimate and harmless. For example, while intrusive ads may look innocuous – they redirect to highly questionable websites (e.g., gambling, pornography, scam-promoting, etc.).

In case of continuous encounters with advertisements and/or redirects, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with AccessibleOptimizer, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
