Even if there is no antivirus application on your computer, in Windows 8 and 10 exists the Windows Defender service, that can stop the StaffCounter application.
To prevent it you need to do the following:
- Whitelist the Downloads folder in the Windows Defender service. Launch the Control panel, Update & Security, Windows Security. Find the virus protection and Exclusions. Add the Downloads folder to the list.
- Download the StaffCounter agent into the Downloads folder and unzip it into a new folder.
- Run staffcounter_install.exe as administrator. (perform a right-click on it and select “Run as administrator”)
- After the installation, the working folder of the StaffCounter agent will automatically be added to the list of exclusions
