Any computer that has a virus should not be used while handling important data, the infected computer should be cleaned and updated as soon as possible. If the computer in question isn't dealt with, an unexpecting victim could lose the important data such as bank account details and passwords.
We believe that a complete operating system reinstallation (formatting) should be considered as a last resort, with the right tools the infected computer can be saved.
