Windows 8.1 Network Connection Error: One or more network protocols missing on this computer

Anonymous

Friend's computer running Windows 8.1 is unable to connect to awired or wireless network giving the following error: Problems found: One or more network protocols are missing on this computer. Windows Network Diagnostics is unable to repair the problem.

This problem appeared after Webroot SecureAnywhere Complete was installed and run. It detected several problems (virus, trojan, malware) and it removed the infections. My friend did reboot the computer and since then it became unable to connect.

Has anyone had this kind of problem happen to them, and what if anything, other than restoring from scratch, can be done to regain connectivity.

Thank you.

Computer Specs.

Dell Inspiron 15R-5521

Intel Core i7-3537U@2.00Ghz

8 GiG RAM

64 Bits Windows 8.1

Update: After toying with the TCP-IP protocols, system is now showing an active wireless connection with full strength, yet when a browser its open it brings up an empty page with "This page can't be displayed"

Pinging to yahoo server returns positive with all ping successfully completed.

Using Internet Explorer "Fix connection problems" returns that no problem was found.

Network Connections shows an active Wi-fi state, and with status details showing IPv4 with Internet Connection, not so for IPV6. Media state as Enabled. Speed 144.0 Mbps, and under Activity: Sent bytes: 1,827, Received bytes 2,513. Diagnose option returns no found issues.

Could this be a possible Virus or System Compromised by malware or trojan? Webroot Active and no infections has been detected since original setup and clearing of active infections.
