Either they need the memory or they don't. If they feel like they need to store something to save on network costs then they should store it, and the OS will page it if it isn't used often. The AV doesn't need to take "free ram" except when it tries to guess what the OS will do with disk cache. But by putting it in the AV cache it then prevents other software from using the cache. Just use the OS level disk cache.
