I have version 2.70.31 and I do know that this was present with 2.70.16. Under my processes (CTRL+ALT+DEL), the process System is always showing up 50-60% cpu usage. I used processexplorer from sysinternals and searched the threads for System. I noticed that amon.sys was causing red marks, so I shut off AMON on nod32. When I did that, the cpu usage ceased to exist. Is there a fix?
