Random Dll's Attempting Internet Access

This is very odd. but it seems random .dll files are trying to access the internet only when I am away from the computer for like 15 mins. They attempt this through rundll32.exe or whatever it's called.

I dont' think it's a virus because it's a new Win7 install and have not installed anything odd. Plus Avast has not picked anything up.

But there's no way all these .dll files are trying to access the internet while I'm gone. I mean most of the .dll files are from non-self-updating apps.
