The problems of ttnfd.sys than is not solved, because I did bring my computer in a stage before the infection happened. Nevertheless the ttnfd.sys digged deep in my regystry and all system files got the follwing attributes and is widely spread over my 300 MB registry. Here is an example:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_TTNFD]
"NextInstance"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_TTNFD]
"NextInstance"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_TTNFD\0000]
"Service"="ttnfd"
"Legacy"=dword:00000001
"ConfigFlags"=dword:00000000
"Class"="LegacyDriver"
"ClassGUID"="{8ECC055D-047F-11D1-A537-0000F8753ED1}"
"DeviceDesc"="ttnfd"
"Capabilities"=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_TTNFD\0000\Control]
Does anyone have a solution for this?

I have Norton 360 on my system and it has been telling me for some time now that the "device is not present, not working properly, or does not have all of its....(can't read the rest). Device type is: ttnfd
Plug and Play ID: ROOT\LEGACY_TTNFD\0000
I looked in C:\Windows\system32\drivers folder and it isn't there. I had a money program on my system and since removing it I've had problems, running very slow at times and locking up.
I know this site is for removing this type of file but my system says I need to fix my Device Manager. When I go into that I have no idea what to look for or even what I'm doing?? Help...........
