How to eliminate the No-Light adware-type browser extension
Written by Tomas Meskauskas on
What is No-Light?
While inspecting deceptive software-promoting websites, we discovered the No-Light browser extension. This piece of software is presented as a tool capable of creating a dark mode for simple design websites. However, our analysis revealed that No-Light operates as advertising-supported software (adware) instead.
No-Light adware overview
Adware displays third-party graphical content (advertisements) on visited websites and/or other interfaces. These ads endorse online scams, unreliable/harmful sites and software, and even malware. Some intrusive advertisements can perform stealthy downloads/installations - when clicked on.
It is pertinent to mention that any legitimate products encountered through these ads are unlikely to be promoted by their actual developers. Instead, this promotion is undertaken by scammers abusing the products' affiliate programs to acquire illegitimate commissions.
It is noteworthy that advertising-supported may require certain conditions to run intrusive ad campaigns, e.g., compatible system/browser specs, visits to particular websites, etc. However, No-Light endangers device/user safety regardless of whether it displays adverts.
Furthermore, No-Light has data tracking functionalities. Information of interest can include: visited websites, viewed pages, searched queries, account log-in credentials, personally identifiable details, financial/banking data, etc. The collected data can then be shared with and/or sold to third-parties (potentially, cyber criminals).
To summarize, the presence of software like No-Light on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples
We have analyzed thousands of adware samples; Find My Package For Free, Mobile, Audio Player, and Webpage Text Reader are merely some of our newest finds. This software typically appears legitimate and offers various functionalities. However, these functions seldom work as promised, and in most cases - they do not work at all.
How did No-Light install on my computer?
We found several dubious webpages promoting No-Light adware. Most users enter such sites through redirects caused by intrusive ads, mistyped URLs, pages using rogue advertising networks, spam browser notifications, or installed adware (with browser force-opening abilities).
Intrusive advertisements proliferate advertising-supported software as well. Once clicked on, some of the adverts can execute scripts to make downloads/installations without user permission.
"Bundling" - packing regular program installation setups 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 allowing bundled content into the device.
How to avoid installation of adware?
We strongly recommend researching software and downloading only from official/verified channels. Additionally, installation processes must be approached with care, e.g., by reading terms, studying possible options, using the "Custom/Advanced" settings, and opting-out of all supplements.
Another recommendation is to exercise caution when browsing since fraudulent and malicious content usually appears legitimate. For example, intrusive ads look harmless yet redirect to highly questionable websites (e.g., adult-dating, gambling, pornography, etc.).
If you continuously experience ads/redirects of this kind, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with No-Light, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
