In the "Folder Options" of windows "Tools" Menu, after changing "view panel" to show "Hidden Files & Folders" and after clicking Apply & OK and close the window the computer still doesn't show Hidden Files & Folders. On reopening the Folder Options the Radio Button has gone back to "Do Not Show Hidden Folders & Files". How can I sort it out ?

Depends on the registry policy settings. If your PC is a corporate PC, the Admin has prolly set policies to prevent you messing around.

if this is a personal PC it is possible that a trojan has got to you and placed itself where it doesn't want you to go remove it.

download AVG anti-virus, check if it will help.. search AVG on the web it's free...

Tried AVG. It has not helped.

Can u suggest an anti virus program that can remove it.

Try Kaspersky 7...It is lite and top rated

If it is a Trojabn, nothing removes it in one go because it is active and the active thing cannot be removed. Circular argument but true.

So please read the first stick post in the Spyware forum and post a Hijack This log, please.

i can't how hidden files and folder. please hel me for this problem.

I have used Registry Cleaner for some months now and it found three bad guys for me. Formerly it was listed as CCleaner (Crap Cleaner). It does work, it is free. Google System Cleaner, Registry Cleaner.

try this script file and tell me if it works
