Written by Tomas Meskauskas on (updated)
What kind of application is LogicCheck?
LogicCheck is an adware-type application that generates advertisements and can read webpage contents and browsing history. We have discovered this application while inspecting deceptive pages offering to install software updates. In most cases, apps like LogicCheck are downloaded and installed unintentionally.
LogicCheck adware in detail
Advertising-supported applications like LogicCheck display annoying banners, pop-ups, coupons, and (or) other advertisements. Clicking those ads opens various scams, download pages for shady apps, and other untrustworthy pages. Sometimes, it downloads or even installs unwanted software.
We also noticed that LogicCheck can read sensitive information from websites, such as passwords, phone numbers, and credit card details. Additionally, it can read browsing history. Its developers may misuse that information for malicious purposes (e.g., to access personal accounts, make fraudulent purchases, steal identities).

More about adware
In some cases, adware-type apps operate as browser hijackers. They change the settings of a web browser (such as the default search engine, homepage, and (or) new tab). The purpose of browser hijackers is to promote fake search engines. More examples of adware (apps like LogicCheck) are ActiveHandler, BrowserLaptop, and BrowserDisplay.
How did LogicCheck install on my computer?
Adware is distributed via fake installers, deceptive advertisements, downloaders, and (or) installers for other software. In the third case, it gets installed when users finish software installation without deselecting unwanted offers in "Custom", "Advanced", or similar available settings.
Advertisements can download or install adware when designed to run certain scripts. In all cases, most users download or install adware inadvertently.
How to avoid installation of unwanted applications?
Use trustworthy sources (official websites, direct links) to download files and applications. Do not trust files and apps downloaded from P2P networks, third-party downloaders, shady websites, etc. Also, do not click on advertisements while visiting questionable pages or allow such pages to show notifications.
Deselect unwanted applications (change "Custom", "Advanced", or similar settings) before downloading and installing programs. Usually, adware-type apps (and other apps of this kind) are bundled with free software. If your computer is already infected with LogicCheck, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
