Sounds like something(s) heinous.
You're turning off system restore? If you can't get to it, stop it in the registry:
Code:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\
CurrentVersion\SystemRestore\ set DWORD DisableSR to 1
Disable the service:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sr set DWORD Start to 4.
Looking just outside this box of a home, there's a barbecue on the back porch. Does that inspire?
