I would highly recommend Trend WorryFree Business. This used to be their SMB product, which I've used for years. Very easy to deploy via GPO, domain login script, or direct push through web-ui. I've NEVER had issues with false positives on system files, bad definition updates, out of control processes, etc with this product. Rolled the latest version out to a customer who was on the previous version, and was flawless and painless. A milestone upgrade does require reboots, and disrupts network activity briefly.
I've also used Symantec from v7.5, which is now at 11.x I believe. Not for the feint of heart because it does require a bit of planning to deploy, but protects your environment very well. It has had it's issues with high process utilization, and your server will need to be big and healthy, especially if you scan an Exchange store. This is also relatively rock-solid, but the customer support has been slipping in the past few years, and they've suffered a couple of glitches in the upgrade process from v9 to 10, and 10 to 11, in addition to milestone upgrades in the 11.x area. I will say I've got this product running at work with no issues now for 2 years. I also have had experience with Vipre, but abandoned it because of a release that brought my clients production facility to it's knees with out of control process utilization. I've posted my thoughts/rants on my blog if you are interested: pcnorb.blogspot.com/search/label/anti-virus <http://pcnorb.blogspot.com/search/label/anti-virus> Overall, I would stick with Trend. --- RBASE-L ================================================ TO POST A MESSAGE TO ALL MEMBERS: Send a plain text email to [email protected] (Don't use any of these words as your Subject: INTRO, SUBSCRIBE, UNSUBSCRIBE, SEARCH, REMOVE, SUSPEND, RESUME, DIGEST, RESEND, HELP) ================================================ TO SEE MESSAGE POSTING GUIDELINES: Send a plain text email to [email protected] In the message SUBJECT, put just one word: INTRO ================================================ TO UNSUBSCRIBE: Send a plain text email to [email protected] In the message SUBJECT, put just one word: UNSUBSCRIBE ================================================ TO SEARCH ARCHIVES: Send a plain text email to [email protected] In the message SUBJECT, put just one word: SEARCH-n (where n is the number of days).
