How to eliminate the DomainQuantity adware from your Mac
Written by Tomas Meskauskas on (updated)
What kind of application is DomainQuantity?
DomainQuantity is a rogue application discovered by our research team during a routine investigation of new submissions to the VirusTotal website. We determined that this piece of software is adware from the AdLoad malware family. The DomainQuantity app operates by running intrusive ad campaigns.
DomainQuantity adware overview
Adware stands for advertising-supported software. It enables the placement of third-party graphical content (advertisements) on visited websites and/or different interfaces.
It is noteworthy that specific conditions may be required for adware to operate as designed (e.g., compatible browser/system or user geolocation, visits to particular sites, etc.). However, even if DomainQuantity does not display ads – its presence on a system remains a threat.
Adware-delivered adverts primarily promote scams, untrustworthy/hazardous software, and potential malware. When clicked on, some of the advertisements can even execute scripts to perform stealthy downloads/installations.
Keep in mind that while legitimate products and services may be encountered via these ads – they are unlikely to be promoted by any official parties. It is most probable that this endorsement is undertaken by scammers who abuse the content's affiliate programs in order to acquire illegitimate commissions.
Browser-hijacking abilities are common for AdLoad adware – however, DomainQuantity did not exhibit these traits during our analysis.
It is pertinent to mention that this rogue application might have data-tracking functionalities, as they are standard for advertising-supported software. Targeted information may include: URLs visited, webpages viewed, search queries typed, Internet cookies, usernames/passwords, personally identifiable details, finance-related data, etc. The gathered information can then be monetized through sale to third-parties.
To summarize, the presence of software like DomainQuantity on devices may result in system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples
UpgradeSection, InterfaceComputing, ExemplaryDatabase, and EditExecute are but a few examples of adware-type apps we have analyzed recently.
Software within this classification rarely appears suspicious; it tends to look legitimate and innocuous. Users can be lured into downloading/installing adware by promises of various "useful" functionalities. However, these functions seldom work as promised, and in most cases – they are utterly nonoperational.
It must be stressed that even if a piece of software works as indicated by its promotional material – that is not definitive proof of either legitimacy or safety.
How did DomainQuantity install on my computer?
Adware can be bundled with (packed alongside) regular programs. The threat of unintentionally permitting access for bundled content into the system is increased by downloading from dubious channels (e.g., freeware and free file-hosting websites, P2P sharing networks, etc.) and by treating installations with negligence (e.g., ignoring terms, skipping steps, using "Easy/Express" settings, etc.).
Furthermore, adware is promoted on legitimate-looking download webpages and scam sites. Most visitors enter these pages via redirects generated by misspelled URLs, websites utilizing rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening capabilities).
Intrusive advertisements also spread advertising-supported software. Some of these adverts can be triggered (i.e., by being clicked) to execute scripts that perform downloads/installations without user permission.
How to avoid installation of adware?
We strongly advise researching software and downloading it only from official/trustworthy sources. Installation processes must be treated with care. Therefore, we recommend reading terms, exploring available options, using the "Custom/Advanced" settings, and opting out of all supplementary apps, extensions, features, etc.
Another recommendation is to be cautious while browsing since fake and malicious online content typically appears legitimate and harmless. For example, despite their ordinary/innocuous appearance – intrusive ads redirect to unreliable and questionable sites (e.g., scam-promoting, pornography, adult dating, gambling, etc.).
If you keep encountering adverts/redirects of this kind, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with DomainQuantity, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
