About the defragging, I have my computer on auto defrag every month. I don't want to do it too often because it kills the harddrive. So yes, I have defragged recently. On the SP2 requirements, please elaborate, but if you mean allowing it through the firewall, I've already done that. Don't get me wrong, its only the newer versions that I'm having troubles with. pre-4.4 it worked quite well. I havn't thought of the possibility of a trojan, so I'll let my av's run tonight and post results in the morn.
