What is the best Antivirus for a Windows Domain Network?
For us it came down to Symantec Endpoint Protection and ESET Nod32/Smart Security. Both have excellent central management features, and both score well on detection rates and not sucking up system resources. We went with ESET based on a bad experience with the trialware of Symantec while evaluating both. ESET was cheaper, as a bonus. Goes to show you it's good to try before you buy, which you can do with most business class AV suites.
If the question is "What Antivirus works well with windows domains to have policies and updates managed?" then I'd suggest looking for security suites that will:
- Ability for Group Policy to manage application settings
- Central management for being able to push updates to clients and servers on the network
- Ability to restrict access to settings and passwords to administrators
One example of a product that can do all these things is McAfee's security suite (VirusScan, ePO etc.)
I vote with ESET. Have used it before it became popular. Very small footprint. Easily removed. Renewal is simpler than Trend, and that's saying a lot.
Symantec Endpoint has become very non-intrusive, low profile, and their footprint is now a reasonable size (much smaller). But trying to completely remove it is still a nightmare.
I'm currently working with Sophos - does a really good job and the fact that you can add Network Access Controls in it can be very useful. When we eval'ed several Antivirus Sophos was the only one light enough to work with our complicated software (before I can to work here).
Long time ago I was a big fan of Panda - great install, light and seemless integration in the network. However, I haven't played with it in a few years. It may be worth cheking it out again (my current job did NOT eval Panda unfortunately).
