Go to Tools, select Options, go to the Security tab, remove the check from
the "Do Not Allow Attachments..." selection, click apply and ok.
NOTE: before you open any attachment, you should first save it to someplace
else on your hard drive, then, be sure your antivirus software is up to date
and run a scan on the attachment before opening. Viruses most frequently
come from people we know as viruses usually propagate by sending themselves
to everyone in an individual's address book when unwittingly opened by the
user. Hence, you should be careful of any attachment.
