Mac endpoint Anti-Virus ITSM

I installed a mac endpoint in the ITSM and with it the Mac Antivirus. The problem is, it makes the mac crawl. Unfortunately all Antivirus solutions from other companies I have tried for the Mac have made the machine crawl as well. I have yet to see a good product for the Mac or a necessity. I am going to uninstall until I get a solution to this issue.

We have installed on a Mac for a client and not received any negative feedback. Perhaps you have a general issue with Mac?
