What is NonLight?
Our researchers discovered the NonLight browser extension while inspecting dubious software-promoting websites. While this piece of software promises to enable dark mode for simple design webpages, NonLight operates as adware instead.
NonLight adware overview
Adware stands for advertising-supported software. It enables the placement of various advertisements on visited websites and/or other interfaces. The displayed ads endorse online scams, unreliable/harmful sites and software, and even malware. Some intrusive adverts can perform stealthy downloads/installations upon being clicked.
It is pertinent to mention that any legitimate products encountered via these advertisements are most likely promoted by scammers abusing their affiliate programs to obtain commissions fraudulently.
It must be stressed that even if adware does not run intrusive ad campaigns - its presence endangers device/user safety regardless. Advertising-supported software may require certain conditions to operate as designed (e.g., compatible browser/system specs, visits to particular websites, etc.).
What is more, NonLight collects private data. It may target browsing and search engine histories, account log-in credentials, personally identifiable details, credit card numbers, etc. The gathered information can then be shared with and/or sold to third-parties (potentially, cyber criminals).
To summarize, the presence of software like NonLight on devices can result in system infections, severe privacy issues, financial losses, and even identity theft.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Combo Cleaner.
We have analyzed countless adware samples; Mix Colors, Gallery, and ClickDark are merely a couple of our latest finds. Advertising-supported software typically appears legitimate and offers "useful" features. However, these functions seldom work as promised, and in most cases - they are utterly nonoperational.
How did NonLight install on my computer?
We obtained NonLight from a suspicious software-promoting webpage. In addition to such sites, advertising-supported software is pushed through online scams. Users enter websites of this kind primarily through pages using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware (with the ability to force-open browsers).
"Bundling" - packing regular program installers with unwanted/malicious additions - is also used to distribute adware. Download from untrustworthy sources (e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc.) and rushed installations increase the risk of inadvertently permitting bundled content into the system.
Intrusive adverts proliferate adware as well. When clicked on, some of the advertisements can execute scripts to perform downloads/installations without user consent.
How to avoid installation of adware?
We strongly recommend researching software and downloading it only from official/verified channels. Installation processes must be approached with care, e.g., by reading terms, studying possible options, using the "Custom" or "Advanced" settings, and opting-out of all supplementary apps, extensions, tools, etc.
We advise being cautious when browsing since illegitimate and malicious content usually appears ordinary and harmless. For example, intrusive ads look innocuous yet redirect to unreliable/questionable sites (e.g., gambling, pornography, adult-dating, etc.).
In case of encounters with advertisements and/or redirects of this kind, inspect the device and immediately remove all suspicious applications. If your computer is already infected with NonLight, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
