Start Outlook Express.
.. On the Tools menu, click Options.
.. Click the Security tab, click to clear the Do not allow attachments to be
saved or opened that could potentially be a virus check box under Virus
Protection, and then click OK.
To better protect yourself from viruses, its a good idea to leave this option
checked unless you definitely want to open the attachment.
Another way to help protect yourself from email viruses infecting your computer
if you use Outlook Express is to disable the Preview Pane. There are certain
viruses that will infect a computer even if you just preview the message. To
disable the preview pane:
Start Outlook Express
.. Click on View, Layout
.. Uncheck the Show Preview Pane, and then click OK.
A quick way to toggle your Preview Pane on and off is by right clicking a blank
area on your Toolbar and select Customize. You will find the Preview in the left
pane and just click Add.
This will put a Preview button on the Toolbar. So when downloading email, turn
the preview off and when you have deleted any unwanted email, you may turn the
preview back on.
