Hi Paul, We block the following extensions on our Groupshield for Exchange: bat,cmd,com,exe,pif,scr,vbs This will block 98 percent of all incoming viruses. Luckily, most of the users are software developers of system administrators, so they now the risks quite well. For that reason, we do not block zip files.....If someone needs to send an attachment that would be blocked, they can always zip it..... If your users are clicking on every attachment by default, without realizing that it could be a virus......then I would definitely block the zip files as well. Good luck, Dennis Appelboom marviQ _____ From: Farrugia, Paul [mailto:pfarrugia@xxxxxxxxxxxx] Sent: donderdag 29 januari 2004 17:21 To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Way OT - Blocking attachments with McAfee GroupShield Hello, Sorry for the OT question but the McAfee group at Yahoo is useless..... This question is for those of you that are using Group Shield (if there are any of you out there). How do you handle blocking attachments? Do you block everything or a limited file extension? What do you do when a legit file attachment is blocked? I know you can save it and then pass it on to the user but is that my only option? Thanks in advance for any advice Paul
