I'm using Norton 360, and many times when I go on, ccsvchst.exe takes up a HUGE amount of my CPU, and sometimes it stays like that for hours! What do I do? My laptop is a 2009 MSI, and runs Windows 7 Ultimate 32-bit. 4GB Ram, and Intel Core 2 Duo Proccesor at 2.2 GHz. If someone can help, please do so. Thanks!
