Antivirus for Lotus Notes client

We have good old Symantec version 10 something which is killing some client machines stone dead with anything from 10% to 100% cpu usage. This is a very old problem that Symantec never fixes.Does anyone know a client side AV program that works with Notes? I don’t think server AV is good enough because client machines also pick up e-mail via pop3.

Subject: Try install SEP 11

Symantec Endpoint Protection (the upgrade from SAV 10) is way better. Just make sure you get the MR3 release or higher.
