A network is protected from e-mail viruses through the use of a sacrificial server. Any executable programs or other suspicious parts of incoming e-mail messages are forwarded to a sacrificial server, where they are converted to non-executable format such as Adobe Acrobat PDF and sent to the recipient. The sacrificial server is then checked for virus activity. After the execution is completed, the sacrificial server is rebooted.

A protective system or apparatus for use in vascular procedures includes a tubular guidewire, a control cable slidable within the tubular guidewire, and a sheathless filter. The control cable is attached to a distal end of the sheathless filter and the tubular guidewire is attached to a proximal end of the sheathless filter. Selective displacement of the control cable radially expands the sheathless filter to create a proximal exterior convex primary filter surface that is positionable downstream from a site of a vascular procedure. The sheathless filter also presents a distal interior concave secondary filter surface. Preferably, the sheathless filter is constructed of a braided wire framework in the form of a tube over which woven polymer fibers or strands are applied to create a filter mesh having a softer filter surface.
