we have been hit by a cryptolocker variant - all files end up with an extension .lock or something like @india.com.lock I've tried a few of the decryption tools on your site without success as i'm not sure of the variant of this type. Is there a way to submit a sample of an unencrypted and encrypted file type? It also leaves a text file in the root of each folder !!!! READ THIS IMPORTANT !!! which is a request to pay the ransom in bitcoins.
