On access virus scanning on Servers?
Necessary or not?
I ask because I'm covering for the technical staff at another school at the moment, and will be tomorrow as well. They are having a ton of problems with system slowdowns, and slowed down a lot about 10 minutes ago. Checking the error logs on the servers and I think it may be down to the McAfee virus scanner on-access scanning, as this has a lot of errors in the event log around the time the slow-down occured.
Not that I'm going to make the change myself, as it's not my system to meddle with, but I'm just interested if it's considered essential to have on-access scanning enabled on the servers or not, so that I may be able to make a recommendation to the staff working here.
