DHCP Client wont start after removing virus in AFD.sys file!!

I have problem on pc that had viruses removed but now can no longer obtain an ip address.  After running CCleaner, Combofix, Malware Bytes, Super Anti-Spyware and TDSSKiller.  I believed I was home free until running one last scan with Microsft Security Essentials and removing win32.sirefef.gen that was detected in afd.sys.  After removing and rebooting I no longer can start dhcp client service, hence not receiving an ip address.  If I give a static ip address, I still cant connect.  I have replaced the afd.sys file with one from a different XP pro system.  Please Help!!

go into internet options click the connections tab go into lan settings and make sure the virus change your proxy settings this happens alot. are you able to ping websites or just unable to get online with IE. Also go into the properties of the dhcp service click dependencies and make sure all of the dependencies are started first. then try to start dhcp service again.

Have you tried going into device manager and deleting your network driver and then reinstalling it. There may have been infected files in the driver. Also try using Combo fix to remove virus. It works great and at a low level removing everything the first swipe.

Did you check to make sure your Hosts file is clean?

Can you ping 127.0.0.1? if so then continue below, if not re-install your TCP/IP then continue below.

From command prompt run these commands

netsh winsock reset
ipconfig /flushdns
arp -d *
ipconfig /release
ipconfig /renew

Please try using the menu options (3-6) in "RogueKiller" to effect the repair.

You may also have damaged or lost windows files.  Run SFC /scannow and have your XP Cd handy.

@jmaggio322,
"Proxy Fix" is menu item #4 in RogueKiller - already mentioned.
