Delete your copy of ComboFix, download a new fresh one and then:
1. Close any open browsers.
2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
3. Open notepad
and copy/paste the text in the quotebox below into it:
C:\Windows\winsxs\x86_microsoft-windows-winsock-core_31bf3856ad364e35_6.1.7601.17514_none_d9efac7dbcaf385b\afd.sys | C:\windows\system32\Drivers\afd.sys
Save this as CFScript.txt
, in the same location as ComboFix.exe
Refering to the picture above, drag CFScript into ComboFix.exe
When finished, it shall produce a log for you at C:\ComboFix.txt
which I will require in your next reply.
