Spyware?

When i try to double click my c drive, the window pop up..
any idea how to solve it?

Your file associations are fubar'ed.

Have a look here: http://www.dougknox.com/xp/file_assoc.htm

There are a few registry files there that'll help restoring normal functionality.

i try downloaded the following files and copy the files to registry.

Directory Extension Fix (Restores defaults to HKCR\Directory)
Drive Association Fix (Restores default settings for hard drives)
Folder Association Fix (Restore default associations for File Folders)
LNK (Shortcut) File Association Fix (Restores Default Shortcut Behavior)

but still cant work

Several other things might be corrupted too..
Does regedit.exe still work? File associations are kept in the HKEY_CLASSES_ROOT registry hive.
Does IE or FF still work?

Have a search around here or google for "file associations", you're not the first one to whom this happens too, probably not the last either ;)

yes both regedit and IE and firefox is working.

hm..
cant seems to get it right

Try this then run windows update:

TweakUI has a facility for repairing file associations:
