At my old job, we used Computer Associates eTrust Exchange antivirus for 4 years with no issues whatsoever. Highly Recommended. This link may be of some help to you as well - April 2004 ranking of the top 16 AV suites for Exchange. http://www.msexchange.org/software/Email-Anti-Virus/ <http://www.msexchange.org/software/Email-Anti-Virus/> Edward Sullivan Sr Analyst Windows Technical Services - West Cingular Wireless Office.469.227.2087 _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Evan Mann Sent: Tuesday, September 14, 2004 8:06 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] OT: Exchange AV scanner of choice Little different then the usual AV product of choose question, I'm looking for Exchange specific recommendations. I'm using Symantec Mail Security 4.5 and it's starting to give me problems that appear to be load related. My servers have plenty of power, but I think the AV engine is choking on the massive influx of mass mailing worm e-mails I've gotten recently. I see 2-5k a day now and it's causing services to crash. When they restart, they don't work. I've tested products about 8 months back, but need new recommendations. I remember liking AntiGen (Expensive) and Trend, but not liking McAffee because the UI was non-intuitive and slow (java).
