MMmmm, nothin like a digitized cookie!
Alright, you're halfway there. Now that you know those 'links' are with extensions, you can go into you registry and figure out which extension is causing all the trouble.
Code:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Extensions\
In this location, you can find a folder (key) for each Extension installed for Internet Explorer. I think you can just delete the folder (key) of the extension that is causing trouble. (For example, delete the '{FF059E31-CC5A-4E2E-BF3B-96E929D65503}' key if you thought the Microsoft Office Research button was causing the problems.

Now, as for your sites not loading...
(1) Clear your cookies, they might be corrupted. (Note: You'll have to log in to websites all over again.. your login/pass will be 'forgotten')
(2) Maybe you have blocked out certain sites in a HOSTS file. (some programs will create a HOSTS file for you). Check to see if you have a 'HOSTS' file here:
C:\WINDOWS\SYSTEM32\DRIVERS\ETC
IF you find a file like that, rename it. See if the problem goes away. (I'm not sure if you have to restart your computer or not)
(3) Got a router or cable/dsl modem? Does it need a reset? (or does the router need an updated firmware?)
(4) Can you give an example of a site (or sites) that
always is broken? Maybe there is something in common.
(5) What if you use a different browser? What if you tried
Mozilla Firebird at least for testing. If you still get 'page cannot be..." errors, then you know it isnt the browser's fault, and rather the router/modem/networking/etc
Try those out if you have a chance!
