My only antivirus is AVG and ZoneAlarm is my firewall. I exclude my entire data drive from scanning. AVG automatically scans files that I download and CDs/DVDs that I insert.
Process Explorer and Task Manager agree that I'm using about half of my RAM and 60% of my CPU. Nothing resource intensive in the background.
I haven't timed Calibre opening, but would believe 51 minutes. It tends to be ask it to do something, go load the dishwasher, come back for the next step, etc.

Like the 51 minutes, 60% CPU usage is extraordinary on a quad core system.
What % of the CPU is being used before starting calibre, and what's contributing to that 60% usage - is it calibre or something else, eg interrupts & DPCs.
I think the Calibre debug is reporting that you are running 32 bit windows,

Which given what you've said about your system configuration surprises me. What does Control Panel->System and Security->System report - and if you are running 32bit Windows I'm not sure that it can address more than 4GB of the 8GB of installed RAM.
