I have experience with both. Right now we are using Network Associates Total Virus Defence Suite, which include Netshield for NT/2000, Groupshield for Exchange and Virus Scan 4.5 for the Desktop PC's. I have found it to be very effective in removing/blocking/quarantining email borne virus threats, however there are some minor issues to be aware of: Netshield, although being able to download the DAT file and save them for later use, ie in a shared folder for the desktop clients using Virus Scan 4.5 to update from, a hotfix is required to be obtained from NAI to resolve the issue of Netshield not downloading the "Update.ini" file that allows the client pc's to correctly process the update of the DAT files. Once this is done we found all instances of Netshield and VirusScan4.5 updated correctly and caught all viruses, including the most recent "Bugbear" virus. Daily checks are highly recommended. Forget weekly, the DAT file version can sometimes change twice in the week. -----Original Message----- From: Stephen Hartley [mailto:shartley@xxxxxxxxxxxxxxxxx] Sent: 17 October 2002 23:31 To: [ExchangeList] Subject: [exchangelist] RE: Anti-Virus revisited http://www.MSExchange.org/ We have been using eScan (www.mwti.com) since October last year when several of my clients got "hit". Not one of them has been infected with a single virus since then - whether the virus signatures were up to date or not! Let's face it, most viruses these days are e-mail borne, so if you are scanning incoming messages and blocking "bad" attachments, 99% of your troubles will be solved. Around 80% of the viruses coming into my machine (but being blocked!) are coming from machines supposedly protected by Norton's Antivirus - says something about that product me thinks! The content management is a real bonus & simple to manage!

I would appreciate any comments both good and bad on Norton' Exchange product. I would especially appreciate feedback from anyone that has had experience with both.
