Hello and Welcome to the Webroot Community!

Are you using a firewall that has a banking mode such as Online-Armor?  Banking mode would become enabled when trying to type Ctrl-V but Ctrl+B was pressed.  When that happened only my default search page e.g. Google could be reached, but not Yahoo or MSN.
 
If the above is not your situation then don't read this post!  :D  (just trying to help.)
