What is SpeedChecker?

SpeedChecker is a potentially unwanted adware program that injects ads into the user's browser. This includes inserting into web pages or displaying ads over parts of existing web page advertisements, banners, coupons or text links that would not otherwise appear. It will communicate with the adware's servers to check for new offers and the placement of offers as well as monitoring and recording the domain name of each page the user views, the advertisements that appear on these pages and the ads the user clicks on. In addition the app may display alerts and popups for updating or installing new applications many of which are ad-supported browser extensions.


During setup, the program registers itself to launch on boot through a Windows Schedule Task in order to automatically start-up (this is typically done to avoid any UAC prompts). It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. It adds a Browser Helper Object (BHO) to Internet Explorer. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). In the Mozilla Firefox browser, it will add an add-on. The main program executable is SpeedChecker.exe. Typically most users end up uninstalling this just after a few days. The software installer includes 148 files and is usually about 3.28 MB (3,440,086 bytes).
