[QUOTE=hoonkid04;2714734]Back up your system now.[/QUOTE]
I think that’s about the best advice anyone can give.
This new generation of malware is particularly insidious and given the fact that it hides until it’s too late you can never be too careful.
Attached or cloud storage is unfortunately no good either as CryptoLocker will infect files on these as well.
For anyone that’s concerned following this story I’d recommend scanning your system sooner rather than later with the free version of Malwarebytes which can detect and remove this ransomware. Especially after seeing how high those infection rates are and how prevalent this is becoming.
Unfortunately nothing at present can recover already encrypted data but at least if CryptoLocker is removed the damage can then be halted.
