A client of mine has a virus scanner (McAfee) installed on his Windows Server 2008.
The server has following services active: Exchange, Domain Controller, DNS, print services, file services, DHCP.
For some reason the server is unstable (crashes, slow responses, high memory usage) and I'm suspecting the virus scanner of being the guilty one.
Therefor my question: is McAfee a good virus scanner for a file server that hosts many small files (< 2 MB)? Or is there a better for this situation?
What are the things I should pay attention for when (re-)installing a virus scanner on this kind of server?
