Solve : BSOD. Rootkits. Trojan.?

Answer»

I have run into a bit of a snag trying to revive my computer that keeps getting a BSOD ~20 seconds after windows startup.

I am running XP SP3

"STOP: 0X0000008E (0xC0000005 0xA12AFB75 0x9F0F47E8 0x00000000)"
I get different STOP errors each time I crash

Here is what happened:

I was browsing the internet lastnight when my start bar and start menu changed from XP default to the 'classic windows' style. I restarted my computer and a few seconds after windows put me at my desktop I got the BSOD as DESCRIBED above. I booted up in Safemode then I attempted to open "Malwarebytes' Anti-Malware" however it would not open. I then opened 'SUPERAntiSpyware' using its alternate start (normal start would not open EITHER) and scanned my computer. It came up with:

Trojan.Dropper/SVCHost-Fake
Rootkit.TDSServ
(with 57 entrys for the rootkit)

I removed them all (+ some tracking cookies) and then restarted. booting back into safemode
and was then able to open Malwarebytes Anti-Malware which came up with the following:

1 infected registry KEY:
HKEY_LOCAL_MACHINE\SOFTWARE\tdss (trojan.Agent)

2 infected registry data items:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogo\userinit (Trojan.Agent) Data: C:\windows\system32\
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogo\userinit (Trojan.Agent) Data: system32\

1 infected file:
C:\windows\system32 (Trojan.Agent)

all of which were 'Quarantined and deleted successfully'

I then rebooted and ran windows and got the same BSOD.

after some reading online I was told to use the minidump feature of XP to find what was left (I was told most likely a rootkit that I can't find). I was however unable to open the .DMP files. I searched and found I had to download a viewer (Horrible idea Microsoft) which I am unable to do due to the computer BSODing when im not in safe mode.

I am posting this from a different computer. I am in the process of typing out the logs. They will be posted in reply to this message asap.When I first had this problem I stoped the scan and removed the files as they came up, as a result I have several logs for super antispyware.

Here are my logs:
