I'm using ePO 3.6.1 and all machines running VirusScan 8.7 wether on Windows 2003 or 2008 use 100% of the CPU during scheduled weekly full scans. Most are base servers with no additional software installed so not sure that there would be any additional exlusions to add. I've tried lowering the system utilization in the task with no change to the CPU usage. Any other idea's how to lower the CPU usage? I'm on patch 3.
