Winsock error

Cannot connect to internet with browser. Outlook email working fine. Winsock diagnostic says: Error attempting to validate the Winsock base providers: 2; Not all base service provider entries could be found in the winsock catalog. A reset is needed. I have done all the resets I can find, and nothing has helped. I have also done various malware/antivirus scans and found nothing. I have deleted the network adapters – no help.
Does anyone have an answer?
