File managers

File managers, help users to open, move, copy, rename or delete files and folders. Examples of file managers are tools like Windows Explorer or Finder on a Mac.

Virus scanning

Antivirus software scans a computer system, either when activated or automatically at a specified date and time, and identifies potential viruses. Many antivirus software programs can also delete or fix potential threats once they have been identified.

Firewall

A firewall is a network security system that monitors incoming and outgoing network traffic and blocks content based on predetermined rules. It works as a barrier to protect the users on the network from untrusted or undesirable content, typically from the internet.

System monitoring

System monitoring is used to monitor the resources and performance of a computer system, such as central processing unit (CPU) usage or the amount of free RAM (random-access memory).

Task management

Task management software provides information about the processes and applications currently running on a computer. This can be used to identify why a computer may be running slowly. It highlights all tasks that the CPU is currently performing, including those that are hidden from the user.

Disk scanning and repair

This allows a system to detect and, if possible, recover from physical errors on the disk. It scans disk surfaces for defects and marks those sections as unavailable to prevent the rewriting of data and data loss.
