I just became aware of this myself.
Cryptolocker - It will encrypt all your files and no one has been able to reverse the encryption as of yet.
This is apparently the ultimate malware/virus that really can destroy all your files unless U pay a $300 ranson.
This is for real, not like others that could just be deleted from your computer.
Check up on google and youtube to find out about it.
I know this is not a virus/malware forum but, everyone, everywhere needs to know about this.
Backups definitely need to be done daily for sure now, but not a backup drive connected to your machine, those files will be encrypted also..
