How to remove the SystemWalk adware from your operating system

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

What is SystemWalk?

While inspecting new submissions on VirusTotal, our research team discovered SystemWalk. We installed this application onto our test system and determined that it operates as advertising-supported software (adware). We also learned that SystemWalk is part of the AdLoad malware family.

SystemWalk adware

SystemWalk adware overview

Certain specifications (e.g., compatible browser/system or user geolocation, visits to particular websites, etc.) might need to be met for advertising-supported software to deliver advertisements. However, even if SystemWalk (or other adware) does not display ads - that does not mean that its presence on a system is harmless.

Adware-delivered adverts promote unreliable/harmful websites and software, online scams, and even malware. Furthermore, some intrusive advertisements can download/install software stealthily - once clicked on.

Note that it is improbable for reputable developers to use adware to endorse their products, yet legitimate content can be encountered through these ads. This is primarily done by scammers who abuse the products' affiliate programs to obtain illegitimate commissions.

What is more, SystemWalk may have other functionalities. AdLoad adware often has browser hijacker traits, although we did not observe SystemWalk exhibiting any.

Advertising-supported software usually has data tracking abilities, and this app may have them as well. Information of interest can include: browsing data (visited URLs, viewed pages, searched queries, etc.), personally identifiable details, usernames/passwords, credit card numbers, and so on. The collected information is monetized via sale to third-parties (potentially, cyber criminals).

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

Adware examples

DataCharacterDynamicInterface, and CommonOperation are merely a couple examples of the adware we have analyzed recently.

Advertising-supported software typically appears legitimate and offers "handy" features. However, these functions seldom work as promised, and in most cases - they do not work at all. Therefore, not only is adware useless, but it also endangers device and user safety.

How did SystemWalk install on my computer?

Adware is distributed using a wide variety of dubious and deceptive methods. This software can be bundled (packed together) with ordinary programs. Download from untrustworthy download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, etc.) and rushed installations - increase the risk of allowing bundled content into the system.

Fake Adobe Flash Player updaters/installers are also used in distribution. Intrusive adverts are used to proliferate advertising-supported software as well. Once clicked on, some of these advertisements can execute scripts to make downloads/installations without user permission.

Adware may have "official" promotional sites, and it is also pushed via scam webpages. These websites are typically accessed via redirects caused by pages using rogue advertising networks, spam browser notifications, mistyped URLs, intrusive adverts, or installed adware (with browser force-opening capabilities).

How to avoid installation of adware?

We strongly recommend researching software and downloading only from official and verified channels. Furthermore, installation processes must be approached with care. Hence, we advise reading terms, studying possible options, using the "Custom" or "Advanced" settings, and opting-out of all additions.

Another recommendation is to be vigilant when browsing - since fake and malicious content tends to look harmless. For example, intrusive ads appear legitimate yet redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, etc.).

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