To add to this sentiment, haven't most/all the viri/malware pushers switched from an email delivery vector to drive-by downloads? I can't recall the last time I saw a viral email attachment. I see and hear of drive-by attempts quite frequently. I see and hear of hyperlinks to malware inside spam. ClamAV won't help here. But the methods mentioned above will. -- Stan
