Specs: Windows XP
Ok so recently my computer (A 2005 HP model) was infected with a host of trojans and other items that changed things in the registry and made it so no usb devices would connect to my computer or even show up in disk managment. While browsing some websites for solutions i was instructed to rename the Mounted Devices hive in HKEY_LOCAL_MACHINE/SYSTEM/MountedDevices i added a one at the end of the hives name and was instructed to reboot. Once I did (surprise!) I found I couldnt log in to XP as the computer froze on the blue xp welcome screen. Running in safe mode is no help as i still cant make it past the blue screen, HP's System recovery on my D drive is missing a file it apparently needs. I do have the recovery/startup discs but i dont know how to use them if i cant log in. Help me, I'm apparently a tech for not creating a backup (although i do have a recent system restore point i could use if i knew how). Also, i have been able to acces my drives (sort of) via booting XP Recovery Console in Safe mode, however i dont know what i should be doing, and when i try to access my c drive it asks for an admin password, when i enter mine it says its invalid. Please help this computer is vital to my schoolwork. Thanks

EDIT: Ok ive been looking around the web and i think i can fix it. Is there any way i could rename the filename i changed using the XP recovery console?
If so what do i need to type into the console?
