My PC was hit by a virus (may be Bloodhound.Packed.Jmp) which caused windows not to show hidden files. If I change that option in "Folder Options" it goes back to "Don't show..". Now, the machine is clean, however, the problem is still there.
Any help is appreciated.
Regards,

Here's a web page where the same problem occurred:

There's at least one entry in the thread (there may be more than one, it's a long thread!) that gives a solution that worked for some:
If anyones still having trouble, heres a fix that worked for me after I got the RavMon virus:
1. Click Start -> Run& (or press Windows key + R)
2. Type regedit and click Ok.
3. Find the key: HKEY_LOCAL_MACHINE\SOFTWAR
4. Look at the CheckedValue key& This should be a DWORD key. If it isnt, delete the key.
5. Create a new key called CheckedValue as a DWORD (hexadecimal) with a value of 1.
6. The Show hidden files & folders check box should now work normally. Enjoy
