Cryptoviruses

My company is seeing a lot of our clients encountering these, and the previous IT job I had we had a couple of sites get hit.

A few recommendations:
A.) Get a good AV program and keep it up to date
B.) Never, ever pay the ransomers
C.) Keep your files backed up. The virus encrypts the files, but does not infect the files themselves. The backed up copies will be clean. It typically targets files with extensions that make them obviously important but nothing that will break the computer itself (like Word docs, Excel spreadsheets, etc).
D.) If you do not have the means for a backup solution, go with Google Docs or Onedrive. You can typically edit the files from within your browser as well.

I only post this because I keep seeing these things pop up
