Yes, this is a bad bastard. It's especially bad news because it will seek out all drives that you can see from Windows Explorer
and encrypt their contents too. So, if as most of us have done in the past, one backs up to another hard drive visible to
Windows, the back-up would be encrypted too!
Two possible solutions, one of which I have implemented after reading about this thing a few days back:
i) Make an external portable hard drive your back-up drive and disconnect it after performing the back-up;
ii) Back up by imaging the hard drive.
There are tools freely available to remove the crypto virus from your system BUT your files cannot be decrypted by
anyone other than the criminals. Naturally, the police ask that we do not pay the crims but some people view the loss
of some data more costly than the fee (said in the report I read to be BC2 - two Bitcoins valued around $280).
Whilst this virus is in the wild and there is potentially a risk that anyone could be affected, those who visit high risk
web sites are those asking for trouble.
If you like boobs and bums so much that you have to seek them out online, best do so on a system not connected
in any way to computers or hard drives containing your treasured family snaps or crucial family, business or legal
documents... Also be wary of running downloaded software and using USB pen drives.
Here's a video of this sucker running. It looks like Sophos could block it.
