Can't open notepad...urgent

I can go to start>accessories>notepad, and it will open.

But, when i double click on a notepad file, it won't open. It doesn't do anything. Yes, those files are set up to open with notepad. I can right click on these files and open with WordPad, but they won't open up in Notepad.
I can also have Notepad open, and do a file>open and open these files. The only thing that doesn't seem to work is double clicking on the .txt files themselves.

Any suggestions?

 

Operating system?

 

Sorry, XP Home

 

Try running this to repair the text file association:

Nope, didn't work.

 

Search for Notepad.exe. Be sure there are at least 2 copies, one in Windows and one in Windows\System32 folders. Copy to whichever is missing.

 

There is one in /windows/ notepad.exe

There is one in /windows/system32/ notepad.exe (created 2001), which is weird considering I reformatted and reinstalled XP a few weeks ago

There is another one in /windows/system32/ notpad.exe (created yesterday evening, yes, it's notpad, not notepad)

The two in /system32 are slightly different File Versions, but they're both 67.5kb.

Any suggestions?

Thanks a lot.

 

You probably have a worm:
