I bet it is AV issue, also make sure that you have latest SP and RU applied

In your screendump i noticed a flat cpu line before you took the screendump and suddenly a spike to 99% which might be misleading. Could you start resource monitor and see what process uses a lot of cpu (on average)?
Any other MS Exchange features or other software installed on this CAS server?

Great you've found it. Should you reinstall the av make sure you exclude the paths or programs of exchange, otherwise it keeps scanning those in its realtime protection.
