My machine having WINDOWS XP SP2 OS has been infected by some kind of virus which has changed extension of all the files (like .doc, .xls, .jpg, .pdf) to .crypt. So now the files are all like .doc.crypt.

Next, if I rename this files and remove the extension, the file is not recovered. The file seems to have got encrypted in some way or it has corrupt data inside it.

I am not able to make out which virus has such a behaviour because I have tried anitivirus like NAV, AVG and some other but none of them can detect this problem and help me to recover the files.

Kindly send any information about this problem and how to recover infected files.

You need to change your File Associations.

My Computer, Tools menu, [Advanced], [Edit] for each Actions in the list.

Screenshot shows example for Open ZDL File-Type.

In screenshot, the Editing action... dialog shown. I included this because Avery forgot to put the %1 in quotes. Had to add the quotes as shown ("%1")to get the File Association to work. This is an error that other software installs make.

When you do this, before you edit anything, you should see exactly which application .crypt is being associated with. Try uninstalling the application BEFORE you do any editing in File Associations. This MAY get back your original associations without editing.
