I run SQL Server 2008 R2 SP1 at this moment.
Thanks for your reply. I'm looking for something official from McAfee that specifically states R2 SP2 is supported.
It's a good question.
https://kc.mcafee.com/corporate/index?page=content&id=KB51569 says that SQL 2008 R2 is supported, but of course no clarification about SP2. However previously I haven't seen any clarification about specific SP versioning.
McAfee Support should be able to give the clarification you require.
