The processes for the web browser are added to the TCPView window.

b. Close the web browser.

What did you observe in the TCPView window?

The processes for the web browser will be removed from the TCPView window.

Answers will vary. The process lsass.exe verifies the validity of user logins to the PC. The services.exe is used to start and stop services and change the default services startup settings. The process svnhost.exe (Service Host) handles the process of sharing system resources. Most of these listed resources are located in the C:WindowsSystem32 folder. If these executables are found elsewhere in the system, they maybe malware, such as viruses, spyware, trojans or worms.
