About  (from Symantec)

Scans your computer for problems and recommends how to fix them.


The most common release is, with over 98% of all installations currently using this version. 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). 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 Norton PC Checkup.exe. The setup package generally installs about 77 files and is usually about 31.23 MB (32,742,696 bytes). The installed file Updater.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.
