The short answer is that the content of your files are safe (assuming they were virus free when you backed them up) and the risk of your PCs being contaminated by a virus as a result of Divinsa’s service is very low. The files which you backup are first compressed and encrypted on your PC. They are stored on Divinsa’s servers in this compressed and encrypted form. There is no known virus which can decrypt your files, insert itself, and then re-encrypt your files so that when you transmit them back to your computer (on a restore) and un-encrypt and un-compress them, the virus can then infect your computer. Rest assured that we do use the latest virus protection software on servers.
