Pretty sure this only works on the personal version of their software. We don't even have an option to deploy a password manager (that I'm aware of) as part of the enterprise Anti-virus product.
The personal versions are what get saddled with "Value Add-Ons" like password managers/website screening with colorful icons/blah blah bullshit bullshit. Most enterprise anti-virus software concentrates on finding viruses and maintaining compliance with whatever policies you have. They are also usually managed by different divisions with different goals.
(Whether or not anti-virus at all is effective is another debate entirely.)
Confirmed, this does not work for `Trend Micro Worry Free Business Security` clients. I do know that the enterprise / business version installs a server on the management machine. I do not currently have access to the box that our version is hosted on to test the exploit there.
