If malware is running on the user's computer, can it change the
destination of a funds transfer invisibly to the user, and still 
have
the verification work?

Theoretically, this is possible. An advanced client-side MITM attack 
could be crafted, altering packets on-the-fly and returning a false 
confirmation page.

i.e.: 

normal response: "$100 USD has been transferred from your () email com to 
evil () hacker com"
altered response: "$100 USD has been transferred from your () email com 
to your () recipient com"
