Whenever an Internet Explorer (IE) browser add-on (toolbar) is installed, you should check your system to see what files are used by this add-on tool, and how it is configured on your system.

C:\Program Files\Alexa Toolbar\uninstall.exe
C:\WINDOWS\System32\AlxRes.dll
C:\WINDOWS\System32\AlxTB1.dll

The setting related to C:\WINDOWS\System32\SHDOCVW.DLL is kind of strange, because SHDOCVW.DLL is a Windows system DLL file. Why Alexa Toolbar is using a Windows system DLL to serve its function directly?
