Wow! I talked with that DBA ... and he doesn't run any form of anti-virus on them. I didn't have the time to talk with him at any great length about it but he said that he's not concerned because he's taken care of that problem in some other fashion.
FYI, I feel like a piker, but I do know that Sophos works fine on a quarter-terabyte of RAM and with realtime scanning with the usual mdf, ndf, ldf, bak, trn, etc. etc. exclusions for data files, log files, and backup files.
I would NOT ever exclude an executable, including sqlserver.exe - what if sqlserver.exe gets infected? What if some does
copy StealingYourData.exe sqlserver.exe
sqlserver.exe is also so small it shouldn't matter - it can be scanned whenever.
