Hello, shane... for a start I think you need a better Firewall. If you check the nod32 log entries you posted you will see that svchost.exe was contacting dangerous websites. Comodo Firewall Pro [free] would have alerted you to the fact that it was attempting to make web connections before any connection was made.
The hijackthis log shows as clean, but you could use it to fix these two orphaned entries:
O9 - Extra button: Net2Phone - {4B30061A-5B39-11D3-80F8-0090276F843F} - http://www.net2phone.com/ (file missing)
O9 - Extra 'Tools' menuitem: Net2Phone - {4B30061A-5B39-11D3-80F8-0090276F843F} - http://www.net2phone.com/ (file missing)

Something must be there, though, to cause svchost to open connections, so to check a little further would you please:
==Get CCleaner from http://www.ccleaner.com/ - and install it in a new folder. You should keep this one for general use. I set the installation checkboxes only to open from the recycle bin. It's neater that way.
Now run CCleaner from the recycle bin rclick menu using its default settings [if you set up CCleaner as i suggested, rclicking the bin icon should give you the Open CCleaner option...].
If you have FireFox open the Applications tab and ensure at least that Cookies and Cache are checked.
Select the Cleaner icon, press Run Cleaner.
Run CCleaner in any other Accounts.
==Please use IE or Firefox to do an online scan at panda:- http://www.pandasecurity.com/activescan/index/
-First Register [otherwise there will be no disinfection, merely detection] with a valid email address for the free online virus scan and follow through.
Unlike Kaspersky this scan does not require Java. Panda will clean only virii, but it is superb at listing other malwares which can then be targeted.
Please ATTACH to your post the log it produces.
