What kind of application is LightSurf?
After testing the LightSurf, our team concluded that it is an advertising-supported app. It displays intrusive advertisements. Additionally, it can read and change data on visited websites. We discovered this site on a deceptive web page claiming that it might be required to add LightSurf to a web browser.
LightSurf in detail
LightSurf is promoted as an app that provides a dark mode for simple websites. However, its developers disclose the detail that LightSurf generates banners, pop-ups, coupons, and other ads. Clicking on those ads can open untrustworthy websites designed to extract personal information and money, distribute malware or other unwanted software, etc.
Also, ads displayed by adware may cause unwanted downloads and installations. In addition o showing ads, LightSurf can read browsing-related and possibly other information. Its developers might misuse gathered data for malicious purposes (e.g., they may sell it to third parties).

Adware in general
Adware is often promoted as useful software that includes some features. In all cases, it displays annoying advertisements. Additionally, software of this type can promote fake search engines (by changing the settings of a web browser) and gather data. More adware examples are File Download Manager, DimMode, and Reduce-Light.
How did adware install on my computer?
We found at least two websites promoting LightSurf: one official and one deceptive. In both cases, this app gets added to an Internet browser after completing the steps provided on those pages. Also, adware can be installed via shady ads, fake installers, and software bundles.
In the last case, users install adware after they complete installations without changing "Advanced", "Custom", or other settings provided in installers. Typically, adware is bundled with free software.
How to avoid installation of unwanted applications?
Download all programs/applications and files from official pages and stores. Do not trust unofficial pages, P2P networks, third-party downloaders, etc. Check downloaders and installers for "Custom", "Advanced", and other settings, and deselect unwanted apps before downloading and installing software.
Also, do not click on advertisements displayed on shady pages or agree to receive notifications from such web pages. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
