PC Usage Viewer shows the times your computer has been active with no previous setup required. The software doesn´t need to run in the background, because Windows tracks login and logoff times (working hours) by default, and the program analyses it.

antivirus scanners and found it 100% Clean. It does not contain any form
of malware, spyware, viruses, trojans, etc. We will re-test each updated
