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

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.

    Hi,

    Are you using Internet Explorer as the default browser? If yes, follow the steps provided.

    I would suggest you to perform the steps provided in the article.

    "Internet Explorer cannot display the webpage" error:http://support.microsoft.com/kb/956196/en-us

    (Applicable for Internet Explorer 11 as well)

    Note: Do not perform Refresh or Reset. Refreshing Windows 8.1 will remove all third party applications installed and it will reset all the Microsoft applications to default. Do not perform Refresh.

    Reset Internet Explorer Settings feature might reset security settings or privacy settings that you added to the list of Trusted Sites. The Reset Internet Explorer Settings feature might also reset parental control settings. We recommend that you note these sites before you use the Reset Internet Explorer Settings feature.

      Registry Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry.

    Hope this information helps. Reply with the status so that we could help you further.

    Thank you Mr. Winston M,  the steps in the link you provided did not produce any positive effects as it had execute some of them already. Nevertheless I re-applied then in the order suggested. I did not regain browser   connectivity.  

    The computer personal data was backed up and a system refresh executed. After completion, Webroot was reinstalled and system connectivity tested with positive result.

    We here concluded that it may had been a Trojan or malware program that once detected and removed took with it system files necessary for the proper operation. Which ones was the question that remained unanswered. The system refresh in windows 8 did it's job effectively, but not so the restore point program which was our first choice but did not work reporting an error or possible corruption of the restore point file itself.

    thank you again for your help and sharing your time with us.
