While waiting for nmsuk to have a look at your latest attachments, you might want to take some time and attend to the following drivers
LVUSBS64.sys 7/26/2008 ... Looks like a Logitech Quickcam driver. See what's out there regarding a more recent driver for this device, otherwise consider uninstalling for testing
hamachi.sys 2/19/2009 ... Usually associated with LogMeIn. See what's out there regarding a more recent driver for this device, otherwise consider uninstalling for testing
L1C62x64.sys 3/31/2009 ... Atheros AR8131 PCI-E Gigabit Ethernet Controller. Update from here
Drivers for Atheros AR8131 and Windows 7
sptd.sys 1/2/2008 ... Usually associated with Daemon Tools or Alcohol 120%, use the uninstaller from here
DuplexSecure - Downloads and remove it (click uninstall)
You also seem to have two potentially competing programs installed and running simultaneously
Avast
and
Another one apparently from Comcast that I'm not familiar with and not sure if they play well together or not. My suggestion would be to uninstall both and replace with
Link Removed due to 404 Error, at least for the time being to help with the diagnostic process. Run a full scan.
You also have another apparent VPN software client installed called
tap0901t.sys 9/16/2009 TAP-Win32 Virtual Network Driver from a company called
Link Removed due to 404 Error not too sure about this one, but you should probably consider updating, upgrading or uninstalling.
