I've been having some issues with webpages being slow to respone (in the time frame of 5-10 seconds) over the last couple weeks.

The pages present a fully loaded, with no errors reported in the IE status bar.

I updated Spybot 2.0.6 and AVG 2012 and scanned with both, defragged and ran scandisk.

I have a Sager M8760 with 300GB Sata 2 HD, 4 GB RAM, Intel I7 720 processor, and do my best to keep background applications limited to those I actually need and use.

With the Task Manager and Resource Monitor as the only open applications, I get a continuous stream of network activity from SDFSSvc.exe, SDTray.exe, and SDUpdSvc.exe (mostly SDTray with SDFSSvc coming in a distant 2nd). the Local and Remote Addresses are reported as "IPv4 loopback". See the attachment.

I'm not understanding why these processes are generating continuous network activity.

Any help??
