McAfee Endpoint performance issues

We recently upgraded to McAfee endpoint threat protection company wide. It is making even the most powerful computers run like **bleep**. 8 core i7 with 16g of ram and a top of the line SSD, Mcsheild ramps to 90% CPU usage any time you open an app. Apps take 5-10 seconds to load after clicking on them. I'm going to call McAfee on this, but I wondered if a else experienced similar issues? It's very frustrating and I wish we would have went with another product instead of upgrading this POS.
