Nevermind, I think I've solved it!
It turns out that the redirect problem which I thought was a symptom of the Just In Time Debugging is, in fact, the main issue and the JIT was the symptom. Perhaps I'm wrong, but either way this is what I did.
When the JIT message came up--I clicked yes.
Microsoft Script Editor appears
Click OK or Break
At the top of the window, open the Tool menu then click Options
Folders appear on the left, highlight and double-click Debugging (possibly Debugger)
Click JIT Settings
Unclick the checkbox that says Enable JIT
This got rid of the JIT pop-up, but not the redirecting problem.
To fix the Redirect:
Return to the Am I Infected?What Do I Do? forum and click the Another Google redirect virus thread and follow the solution posted there (two are offered). The TDSSKiller download worked for me.
It's been about half and hour, and everything is still working.
