Guys,

Sorry I did not come to your site first, I caught TLD4 Malware and used Combofix and TDSSKILLER to remove, they did well but now I have a serious issue with windows. The system now on any mode of boot (Safe Mode with Networking or Normal Logon) fails with the following error and then follows with BSOD. The error messages I receive when I hit CTRL ALT DEL are as follows in order:

1st Authentication Manager Error
A specified authentication package is unknown
2nd Winlogon.exe - Application Error
The Instruction at "0x1001caf2" referenced memory at "0x000500ac" The memory could not be "read"
3rd BSOD
STOP: c000021a {Fatal System Error}
The windows logon process system process terminated....
0xc0000005 (0x00000000 0x00000000)

I can get into Safe Mode (WITHOUT NETWORKING) but that is all I can do. Is there any hope?

Thanks again for your help,


Darren

  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
