Nov 28, · There are measures you can take to protect yourself from viruses. According to Klausner, the best way to avoid getting a viral infection is to stay away from sick people, regularly wash your hands (the right way), and avoid touching your nose, mouth, and face.

Unsolicited executables, documents, spreadsheets and such shouldn't be run inside any organization. If you don't know that something is virus-free, assume it isn't.

Not only do hoaxes spread misinformation and waste staff time and resources, but they can also be embarrassing to organizations whose employees forward them to contacts or customers.
Here's a sample hoax policy:. It doesn't matter if the virus warnings have come from an antivirus vendor or been confirmed by any large computer company or your best friend. All virus warnings should be sent to [insert name] and [insert name] only. It is [insert name]'s job to send all virus warnings, and a virus warning that comes from any other source should be ignored.
