I moved all my clients to Sunbelt Vipre Enterprise. Very reasonably priced, especially with a competitive upgrade. Easy to install, manage, and has uninstallers for most of the other AV products. It also seems to run with a whole lot less resources... everyone was like, "what did you do to my computer, it's running so much faster". The times I've called into support, it's always been someone who speaks english, and for the most part has been very responsive.
