@Kannan_S Norton VPN services may be the culprit. Open Windows services from a run dialog using services.msc . Scroll down the listing of services and find the one labeled Norton VPN. Open its properties dialog and set the start type to disabled. If the services is running set that to stop. Click apply then ok. Reboot and recheck for your issue persisting.
