How to get rid of SampleCheck adware?

Also Known As: Ads by SampleCheck
Type: Mac Virus
Damage level: Medium

What is SampleCheck adware?

SampleCheck generates revenue for its developer by displaying ads and promoting a specific website (fake search engine). Most users download and install advertising-supported software and browser hijackers like SampleCheck unknowingly. Thus, SampleCheck and similar apps are categorized as potentially unwanted applications (PUAs).

SampleCheck adware

SampleCheck in detail

Advertisements (for example, coupons, banners, surveys, pop-ups) displayed by SampleCheck could open download pages for other PUAs or even malicious apps, various scams, shady sites asking to provide personal information. Those ads also could download or even install unwanted software by running executing scripts.

SampleCheck also changes the settings of a web browser to promote a fake search engine. It changes the homepage, default search engine, and new tab URL. Users of hijacked browsers are forced to visit a particular address as long as an app like SampleCheck is present. Fake search engines cannot be trusted - they can promote unreliable pages.

Adware in general

Adware is a type of software that generates annoying advertisements. It is common for adware to be distributed using questionable, deceptive methods. Software of this type can be designed to collect various information about the user. More adware examples are ArchivesTransation, MegaUnit, and OptimalSource.

How did SampleCheck install on my computer?

Pretty often, users download or install unwanted apps through downloaders or installers for other programs with "Custom", "Manual", "Advanced", or other settings. PUAs get downloaded or installed when users download or install programs without changing those settings.

Also, users cause unexpected downloads or installations by clicking on advertisements designed to run certain scripts or through fake installers.

How to avoid installation of potentially unwanted applications?

Download applications (and files) from official websites and via direct links. Avoid clicking advertisements that questionable websites have on them. Check downloaders and installers that have any settings for potentially unwanted applications and deselect them before downloading or installing programs.

If your computer is already infected with SampleCheck, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
