While SPAM is annoying, Viruses are downright destructive.  Fortunately, one of the items available with your MyWinHosting account is email virus detection.  Here's how you enable it:

1. Log into your control panel and navigate to your email panel.
2. On the main, "Mail Service" panel, you will see a bug icon located next to the label, "AntiVirus."  Click it to get to the AntiVirus settings.
3. The settings give you the ability to mark the email as having a virus, delete the virus, or sent the virus to another mailbox.  Pick one.
4. Click "Submit" to save the settings.

The same icon is also located by each mailbox so that you can override the setting on a per mailbox basis.
