netscape 4.61 recognizes file.changed-doc/xls

Do to the increasing threat of viruses, I have added procmail filters to mangle the .ext of attachments so users would have to rename the file after saving the file to disk. This gives our antivirus a chance to scan the file and allows users 30secs to think about what they are doing. What I have noticed is, netscape mail (ver 4.61) recognizes attachments that have been renamed. We sent two seperate emails with attachments, one with test.doc and one with test.xls. Upon receiving the email, the attachment's name was changed to test.1234DEFACED-DOC and test.1234DEFACED-XLS. After double clicking the attachments, netscape mail gives the user the option of opening the file with winword.exe and excel.exe. We also tested with .bat and various other .ext but only winword and excel associated files were recognized. Can anyone else confirm or deny this? Thanks, Chad Thunberg
