What kind of application is SampleLight?

SampleLight adware in detail

Clicking advertisements displayed by SampleLight can open untrustworthy pages. For example, websites asking to provide sensitive information, offering to download shady apps, etc. Also, clicking them can lead to unexpected downloads or even installations (if ads would be designed to run certain scripts).

It is worth mentioning that apps like SampleLight can be designed to hijack web browsers by changing their settings. Most browser-hijacking apps promote fake search engines. It is not safe to use such search engines since they can show misleading results or results generated by untrustworthy search engines.

More about adware

It is common for adware to be promoted as legitimate and useful software. However, most advertising-supported apps get installed inadvertently. In addition to serving unwanted ads, they can collect browsing-related and even sensitive information. Thus, it is highly advisable not to install adware on browsers and computers.

More adware examples are LaunchHistoryResults, InfoMajorSearch, and NetDivision.

How did SampleLight install on my computer?

Adware is distributed using deceptive websites, advertisements, downloaders/installers for other software, and similar methods. Downloaders and installers used to distribute adware have "Custom", "Manual", "Advanced", or similar settings (or ticked checkboxes). Adware gets installed alongside other software after finishing installations without changing those settings.

It is worth mentioning that advertisements can cause unwanted downloads or installations only when designed to run certain scripts. Such ads appear mainly on shady pages.

How to avoid installation of unwanted applications?

Do not trust advertisements, fake "Download" or similar buttons, and notifications displayed on or by dubious websites. Use legitimate pages and platforms to download apps (and files). Do not use unofficial pages, third-party downloaders, P2P networks, etc., and other sources of this kind.

Also, deselect unwanted applications before downloading/installing software (it can be achieved by changing the available settings). If your computer is already infected with SampleLight, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
