Virus keeps encrypted files in following directories:
\Documents and Settings\<user>\Local Settings\Application Data\CDD
\Documents and Settings\<user>\Local Settings\Application Data\FLR
if you cannot find them - make sure you have "view hidden files" option enabled in your explorer, and check all the <user> folders.

if the files in these folders are reported as infected by your antivirus - do not let him to delete or fix it - that's not true - they are not infected, just encrypted.
if other files are reported infected and cannot be deleted - you can try to do a full scan in Safe Mode.
but before that export your "HKEY_LOCAL_MACHINE\SOFTWARE\Fcd" entry into some backup file - you will need it to decrypt your files later. otherwise if you antivirus deletes that registry key - you won't be able to recover your files.

if you provide more info - i could be more helpful.
