How to remove SystemDesignMarket adware and the ads it delivers
Written by Tomas Meskauskas on (updated)
What kind of application is SystemDesignMarket?
While reviewing new submissions to the VirusTotal website, our researchers discovered the SystemDesignMarket application. Upon inspection, we determined that it is adware. This piece of advertising-supported software is part of the AdLoad malware family.
SystemDesignMarket adware overview
Adware enables the placement of third-party graphical content (e.g., pop-ups, coupons, banners, surveys, overlays, etc.) on visited webpages and/or other interfaces.
It is noteworthy that advertising-supported software might not run intrusive advert campaigns if the browser/system or user geolocation is incompatible, specific sites are not visited, or other conditions are unsuitable. However, regardless of whether SystemDesignMarket displays ads – its presence on a system endangers device integrity and user safety.
Advertisements displayed by this software commonly endorse online scams, harmful apps/extensions, and even malware. Some intrusive adverts can execute scripts to perform stealthy downloads/installations – upon being clicked.
Keep in mind that legitimate products or services encountered via these ads are unlikely to be promoted by their actual developers. It is most probable that this promotion is undertaken by scammers who abuse the content's affiliate programs in order to acquire illegitimate commissions.
Additionally, SystemDesignMarket might have browser-hijacking functionalities – as they are common for AdLoad apps, yet we did not note these qualities during testing.
Furthermore, adware typically has data-tracking abilities, and this might be true of SystemDesignMarket. Information of interest may include: browsing and search engine histories, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, etc. The collected information can then be sold to third-parties or otherwise abused for profit.
In summary, advertising-supported software like SystemDesignMarket may cause system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples
We have investigated thousands of adware-type apps; ExtendedOperation, BounceTopics, and RadioDiskInput are merely a couple of our newest finds.
While software within this classification usually appears legitimate and offers "handy" functionalities – it seldom operates as promised. It must be mentioned that even if an application or a browser extension works as indicated by its promotional material – that does not guarantee its legitimacy or safety.
How did SystemDesignMarket install on my computer?
Adware can be bundled with (packed alongside) ordinary programs. The threat of unintentionally allowing bundled content into the device is increased by downloading from dubious channels (e.g., freeware and third-party websites, P2P sharing networks, etc.) and by rushing through installation processes (e.g., using "Quick/Easy" settings, etc.).
Some intrusive advertisements can be triggered (i.e., by being clicked) to execute scripts that perform downloads/installations without user consent. These adverts are also utilized in adware distribution.
Additionally, advertising-supported software is promoted on legitimate-looking download webpages and scam sites. Users primarily access such pages via redirects generated by websites using rogue advertising networks, spam browser notifications, mistyped URLs, intrusive ads, or installed adware (with browser force-opening capabilities).
How to avoid installation of adware?
We strongly advise researching software and downloading it only from official/trustworthy sources. When installing, it is essential to read terms, study available options, use the "Custom" or "Advanced" settings, and opt out of all supplementary applications, extensions, tools, etc.
Another recommendation is to be careful while browsing since fraudulent and malicious online content typically appears legitimate and harmless. For example, intrusive ads may look innocuous – yet redirect to unreliable and questionable sites (e.g., scam-promoting, adult dating, pornography, gambling, etc.).
If you keep encountering advertisements and/or redirects of this kind, check the device and immediately remove all suspicious apps and browser extensions/plug-ins. If your computer is already infected with SystemDesignMarket, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
