AntiGen from Sybari software has taken care of us very well. It has several engines you can subscribe to, Norman, NAI, SOPHOS, CA-IT, CA VET and a worm list they keep. It's pretty good at content filtering, i.e. who's it from, whats the subject, file types, etc.., it also has a nice template setup for deploying across mulitple Exchange servers. Now they'll do SPAM filtering for ya also, but we use another product for that. I run it on all of our Exchange servers, I just looked at our main SMTP server (W2K, Exchange2000 on an XSeries 345), it's catching about 18 - 20 incidents per minute, it's purging most, but quarantining 1 or 2 every couple minutes or so and the server is basically idleing. Every time I see one of these new piece of crap worms come out I whisper to myself 'Damn I love Antigen...' _____ From: Evan Mann [mailto:emann@xxxxxxxxxxxxxxxxxxxxx] Sent: Tuesday, September 14, 2004 7:06 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).
