What Do I Do After I Boot XP With A Boot-Cd? Should I Fix The Blue Screen Of Death? But How? How About A Registry Cleaner? Already Tried "Last Known Good Configuration", Safe Mode But Doesnt Work! Dont Wanna Reformat XP.

I believe I encountered a rogue software last week. Received a pop up for a trojan virus. Ran my AVG software and thought I repaired system. Now windows close on their own. I cannot update windows or any antivirus. I have run AVG, Avast, SuperAntiSpyware and yahoo antivirus….nothing is found. I can not do a system restore, nor can I start up in safe mode (F8). I am running Windows XP. Can someone tell me where to turn next

Hi everyone, i am new here. I have a problem with mi windows Xp with a message of some unable to find register in:

systemroot\system32\config\DEFAULT

I searched in google in another computer and i found this instructions from microsoft website.

I needed a windows xp cd (i got it from a friend) and with the Recovery Console i had to type:

md tmp
copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

delete c:\windows\system32\config\system
delete c:\windows\system32\config\software
delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\default

copy c:\windows\repair\system c:\windows\system32\config\system
copy c:\windows\repair\software c:\windows\system32\config\software
copy c:\windows\repair\sam c:\windows\system32\config\sam
copy c:\windows\repair\security c:\windows\system32\config\security
copy c:\windows\repair\default c:\windows\system32\config\default

and then some other instructions for the safe mode in windows.
However, when i type
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

the console respond with “cannot copy file”

Fine, i searched google again and found this page:

Someone wrote that in that case I should go direct to type

copy c:\windows\repair\default c:\windows\system32\config\default

cause there is no “default” file in the config directory. But when i do that, there is a message “Do you want to replace default file (Y/N)?”

I am confused, there is a default file, but i can not copy to a .bak file?
What do i do now? do replace the file? would there be a problem in the future for doing that?
I can not use windows Xp, not even with the safe mode.
Thanks for any help you can give me, and sorry for my bad english.

I seem to have the worst ever Malware… computer is so slow it barely runs unless on safe mode!! have tried Smitfraud, Mcafee, Sniper, Malware remover, Registry Cleaner, Spydoctor etc etc any others or should I just format?

I have to turn my computer on and off at least a half dozen times before I can get to my desktop. Usually about 3 times before I get the screen telling me that windows was shut down abnormally and giving me several other starting options. At this point, I choose safe mode and sometimes it frreezes midway through loading the drivers and always freezes after loading all the drivers.
With every cycle, the process goes just a little farther with safe mode finally loading or sometimes, I try to let windows start normally with that working as well.
No matter what, whenever I get to a point where I can restart the computer, it's fine from there on. Never any problem on restart. Might I be experiencing some sort of hardware failure?
