Network connection failure caused by damage to tcpip. sys

When I turned on my computer early this morning, anti-virus software issued an alarm saying that tcpip. sys was infected with viruses. Based on the trust in avast, I subconsciously deleted the files. After I click it, I have a little regret. What should I do in case of an accident? It seems to be in the driver directory, and suddenly there is an ominous hunch: Fuck. Indeed, I cannot access the Internet.

The local connection data packet received is 0, and the connection status is all null. Click the repair prompt "querying the TCP/IP settings of this connection failed "...... Silly ~~ Try restarting the local connection. Check the NIC Driver. Run SVN update and try again. The socket is damaged. Copy the TCPIP from your colleague's computer. sys cannot replace the damaged ones. Ask du Niang and try again in a few ways; no way, reload the TCP/IP protocol. I'll go, it cannot be uninstalled. Finally, I found a feasible solution.

1. Start --run --regedit.exe, open registry editor, and deleteSubkey(The computer will automatically generate after restart)
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Winsock
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Winsock2

2. Open the % winroot % \ INF \ nettcpip. inf file in notepad and find: [Note: % Winroot %Represents the root directory of the operating system file, which is generally:C: \ WINDOWS]
[Ms_tcpip.primaryinstall]
Characteristics = 0xA0 <------ set 0x hereAChange 0 to 0x80. Save and exit (if the system is 2000, it is 0x80. skip this step)

3. Open the TCP/IP attribute of the local connection --- add protocol -- install from disk -- browse and find the saved nettcpip. INF (% winroot % \ INF \ nettcpip. INF) file, and then select "TCP/IP protocol" (do not select the TCP/IP version 6 ).
After this step, return to the network connection window, but at this time,"Uninstall" buttonIt is already available. Click the "Uninstall" button to delete the TCP/IP protocol and restart the computer once.

4. After the restart, follow the steps in Step 4 to reinstall the TCP/IP protocol.

5. restart the computer again and solve the problem.
