Of course it can, for example by using a single process environment, with synchronous CPU/fast RAM to maximize banwidth, and hardware related signature matching. It's the same for 3D video cards : floating point calculations for 3D rendering can be made by the CPU. But with dedicated hardware, it's multiple times faster. -- Cordialement, Arnaud Jacques Consultant Sécurité Téléphone / Fax : +33-(0)3.44.39.76.46 Portable : +33-(0)6.24.40.95.03 E-mail : [EMAIL PROTECTED] Securiteinfo.com La Sécurité Informatique - La Sécurité des Informations. 266, rue de Villers 60123 Bonneuil en Valois _______________________________ _______________________________________________ http://lurker.clamav.net/list/clamav-users.html
