What do you exclude from antivirus scans?
I've had a few file servers fail in the last few years I have finally realised its probably be scanning every single file on the network over and over again destroying the hard disk. By default Symantec auto protect scans everything on the file server and the statistics show millions of file read cycles.
So what do people exclude from the auto protect on their file servers? I have removed the roaming profiles which has made a massive difference but was also thinking of excluding doc and xls files. Is this a step too far? The only virus's we have had in the logs in the last 3 years are .exe and .dll ones so I'm hoping to still catch these.
