Defender Pro

Remove Defender Pro
Powered by Reason Antivirus


The most common release is, with over 1% of all installations currently using this version. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. 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). The primary executable is named defenderpro.exe. The setup package generally installs about 34 files and is usually about 55.11 MB (57,788,829 bytes). The installed file AntivirusUpdater.exe is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered. Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows 10. While about 96% of users of Defender Pro come from the United States, it is also popular in Canada and United Kingdom.
