I can't seem to find any info anywhere about antivirus exclusions for different OCS server roles. Anyone have any insight as to where this might be found / if any are needed?
I personally like to exclude the ABS files, and you should follow SQL Server best practices and exclude *.ldf, *.mdf, and *.ndf files. The only recommendation I've seen from Microsoft is that you should not scan conferencing content during peak hours. Pretty much all the other files related to OCS are program files that any modern A/V software should presumably be able to deal with.
