Does webroot have a fix for missing file t8extex.dll? Do I need to upgrade?

A search indicates that t8ExtEx.dll belongs to the FunWeb/MyWebSearch family of potentially unwanted programs.

Go to Control Panel> Add or remove programs and uninstall any of these that are listed:
Mywebsearch Bar
Smiley Central
My Way Speedbar
Search Assistant Mywebsearch
Fun Web Products
Fun Web Products Easy Installer
Weatherbug Companion
 
Also have a peek here!
