Norton PC Checkup is a free diagnostic tool developed by Symantec. It scans Windows for security, performance, and malware in depth. The program provides information about antivirus software installed on the computer, firewall, system updates, overall system performance, the number of applications running with the system, temporary files and malware (viruses, Trojans, spyware, etc.) and the level of security of the wireless network to which the computer is connected.

Norton PC Checkup has a feature that allows you to plan the process of scanning your system from time to time.
