How to eliminate Reduce-Light adware and the advertisements it displays

Also Known As: Ads by Reduce-Light
Type: Adware
Damage level: Medium

What is Reduce-Light?

While inspecting questionable software-promoting websites, our researchers discovered the Reduce-Light browser extension. This piece of software promises to enable dark mode for simple design webpages. However, our analysis revealed that Reduce-Light operates as adware instead.

Reduce-Light adware overview

Advertising-supported software (adware) is designed to display third-party graphical content (various ads) on visited websites and/or other interfaces.

These advertisements promote unreliable/harmful sites and software, online scams, and malware. Additionally, some intrusive ads can perform stealthy downloads/installations once clicked on. Note that any genuine products encountered through these adverts are most likely endorsed by scammers abusing their affiliate programs to obtain illegitimate commissions.

It must be mentioned that adware might not display advertisements if certain conditions are unsuitable (e.g., browser/system or user geolocation are incompatible, specific websites are not visited, etc.). However, regardless of whether Reduce-Light delivers adverts or not - its presence on a system endangers device/user safety.

What is more, Reduce-Light has data tracking abilities. Advertising-supported software usually collects browsing and search engine histories, log-in credentials, personally identifiable details, financial/banking data, etc. The collected information can be monetized via sale to third-parties (potentially, cyber criminals).

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

Adware examples

We have analyzed countless adware samples; MovieholicNino Colors, and OpenCandy are merely a couple of our newest finds.

This software seldom appears suspicious, it tends to look legitimate and harmless. Users are enticed into download/installation and/or purchase with "useful" and "advantageous" functionalities. However, these functions are rarely operational.

How did Reduce-Light install on my computer?

We acquired Reduce-Light from its "official" download webpage. In addition to such, adware is promoted on scam sites. Most users access these websites through redirects caused by pages using rogue advertising networks, spam browser notifications, mistyped URLs, intrusive ads, or installed adware (with browser force-opening capabilities).

Advertising-supported software can also be bundled (packed together) with ordinary programs. Download from untrustworthy sources (e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc.) and rushed installations (e.g., skipped steps, used "Easy/Quick" settings, etc.) increase the risk of allowing bundled content into the system.

Intrusive advertisements proliferate adware as well. Once clicked on, some of these adverts can execute scripts to make downloads/installations without user permission.

How to avoid installation of adware?

We strongly recommend researching software and downloading only from official and verified channels. Installation processes must be approached with caution, e.g., by reading terms, studying possible options, using the "Custom" or "Advanced" settings, and opting-out of all supplementary apps, tools, features, etc.

We advise being vigilant when browsing since fraudulent and malicious content usually appears legitimate. For example, intrusive ads look innocuous yet redirect to questionable websites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with adverts and/or redirects of this type, check the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with Reduce-Light, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
