Error creating registry key:help!! I cant get anything installed!

ok, first of all, my computer was full with spyware, adware, malware, trojans, you name it, so I decided to download a program that could helpme fix it, wait but before that I tried installing Msn messenger 7.0 and it created an error message because i dont have iexplorer 6.0, so I tried to download it but it wouldnt let me it said that there was an error creating registry key code 1009, so I scanned my computer for viruses and thats when i found out all the trash I had. So first I try downloading Spyware Blaster

Error creating registry key:
HKEY_LOCAL_MACHINE/Software/microsoft/Window/CurrentVersion/Uninstall/spywareblaster_is1
RegcreatEx failed;code 1009
La base de registro de configuraciones esta dañada
(my computer is in "spanish", though many things are in english)

so that was the beggining of hell, the only things it let me install were Hijackthis, Xoftspy and I already had spybot, but still they wouldnt fix the problems so I had to do alot manually, I thought if all the trash was gone the error would be fixed, but it seems not, so now i dont know what to do!!! please help me!!!

Ps. the message is always the same, the only thing that changes its the program name
