How to eliminate OpticalTransaction adware from your operating system

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

What is OpticalTransaction?

OpticalTransaction is a rogue application that we discovered while inspecting new submissions to VirusTotal. We installed this piece of software on our test system and learned that it operates as adware. Furthermore, OpticalTransaction belongs to the AdLoad malware family.

OpticalTransaction adware

OpticalTransaction adware overview

Adware stands for advertising-supported software. It displays advertisements on visited sites and/or other interfaces. These ads promote online scams, unreliable/harmful websites and software, and even malware. Some intrusive adverts can even make stealthy downloads/installations upon being clicked.

It is pertinent to mention that any legitimate products encountered via these advertisements are highly unlikely to be endorsed by their actual developers. Instead, this promotion is undertaken by scammers abusing the products' affiliate programs to obtain illegitimate commissions.

Note that advertising-supported software might not deliver adverts if specific conditions are unsuitable (e.g., incompatible browser/system or user geolocation, particular websites are not visited, etc.). However, even if OpticalTransaction does not run intrusive ad campaigns - its presence on a system threatens device/user safety.

Furthermore, OpticalTransaction may have browser-hijacking abilities since they are common for AdLoad adware; however, it did not display any during testing.

What is more, OpticalTransaction likely has data tracking functionalities. Information of interest may include: browsing and search engine histories, usernames/passwords, personally identifiable details, financial/banking data, and so on. The gathered information is then shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of software like OpticalTransaction 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; UniversalHandlerGeneralDisplay, and MinimalEnergy are merely a few examples.

Advertising-supported software typically looks legitimate and harmless. Users are lured into download/installation with various "useful" and "advantageous" features. However, these functionalities rarely work as promised, and in most cases - they do not work at all.

How did OpticalTransaction install on my computer?

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

Advertising-supported software is also proliferated via intrusive adverts. Once clicked on, some of these advertisements can execute scripts to make downloads/installations without user consent. Additionally, fake Adobe Flash Player updaters/installers are used in distribution.

Adware can be bundled (packed together) with ordinary programs as well. Download from untrustworthy sources (e.g., unofficial and freeware websites, P2P sharing networks, etc.) and rushed installations increase the risk of allowing bundled content into the system.

How to avoid installation of adware?

We advise researching software and downloading from official/verified sources. Installation processes must be treated with care, e.g., by reading terms, inspecting available options, using the "Custom" or "Advanced" settings, and opting-out of all additions.

Another recommendation is to exercise caution when browsing since fraudulent and malicious material usually appears legitimate. For example, intrusive adverts look harmless yet redirect to unreliable/questionable websites (e.g., gambling, adult-dating, pornography, etc.).

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