a user says there is some auto deletion of files she had on her windows 10 pc after doing a scan there is no virus or malware found. noticed that the browsers (google chrome, IE, edge) are not able to surf the net even though the wifi internet is connected. refer to some link like internet-connected-but-browsers-not-working-windows-10 however not able to resolve. Anyway to check if her pc is instead hacked by someone or the browsers issue is due to some system files that is non virus or malware related?
Look in the Wireless Network Properties and make sure the network elements (especially Client for Microsoft Networks) are properly enabled where they should be.
