I have the Windows 7 o.s. and caught what Symantec labels as a Trojan in afd.sys. I can no longer get on the Internet. According to Norton, this site has a fix. How would I get that fix. Thank you very much.

We have afd.sys file missing and possibly registry key as well.

Please download SystemLook from one of the links below and save it to your Desktop.
Download Mirror #1
Download Mirror #2

64-bit users go HERE
  • Double-click SystemLook.exe to run it.
  • Vista\Win 7 users:: Right click on SystemLook.exe, click Run As Administrator
  • Copy the content of the following box and paste it into the main textfield:
    :filefind
    afd.sys
    :reg
    HKEY_LOCAL_MACHINE\system\currentcontrolset\services\afd /s
    
  • Click the Look button to start the scan.
  • When finished, a notepad window will open with the results of the scan. Please post this log in your next reply.
Note: The log can also be found on your Desktop entitled SystemLook.txt

Open Windows Explorer.
Navigate to following folder:
C:\Windows\winsxs\x86_microsoft-windows-winsock-core_31bf3856ad364e35_6.1.7601.21712_none_da774a9ad5cea29e
Find and copy afd.sys file.
Paste the file into C:\Windows\System32\drivers folder.

Then...
Download Seven.zip file from here: http://www.smartestcomputing.us.com/files/getdownload/27-registry-network-keys/
Unzip it.
Inside you'll find three files.
Right click on afd.reg file, click "Merge".
Allow registry merge.

Thank you. We did all of this, but the Trojan is still there and there is no access to the Internet. Is there anything else that we should do?
