If you are referring to CryptoLocker, it is not a virus or spyware. It's an encryption a hacker places on all your documents  local and network that encrypts your documents.

There are multiple lines of defense:

1. Installing a good firewall like Cisco, Sonicwall or Barracuda that includes content filtering to inspect packets as they are received and drop suspicious and known file types before they reach your network.

2. There are also some software firewalls that help but we believe a stand alone hardware firewall is best.

3. Installing a web based anti spam service that inspects email before it's received like the content filtering above. We use GFI Mail Essentials Online for this service.

4. Educate your users not to open email that looks irregular and from someone they do not expect. This is just plain common sense feature that some people don't use.

If you get hit with CryptoLocker, there are two solutions:

1. Restore from a backup
2. Pay the ransom and hope they unlock your files.

Hope this helps.
