Microsoft has announced a security patch for its e-mail product Outlook, bowing to pressure to change the relative ease with which viruses spread in its software.
The patch prevents users from running any program or script sent in an e-mail message and warns users when software attempts to access the Outlook address book. The patch will also tighten default security, making it impossible for users to run ActiveX controls and scripts, closing a potentially serious hole in e-mail security.
Simon Moores, chairman of the Windows Forums user association, said, "This is a good interim step but nothing can be truly effective."
But Philip Ryan, head of Infosecurity at security firm PeaPod, warned that even the current measures implemented by Microsoft may not be absolutely failsafe.
