We are currently running a system upgrade to improve your overall experience.
Trend Micro Community will be back online on Saturday, October 19.
In the meantime, you can contact Technical Support here: https://esupport.trendmicro.com/en-us/home/pages/technical-support/contact/home.aspx
See you soon!
We don't have a definite list of supported and non-supported FTP programs. But if you will try to use one and you had encountered a possible conflict with the Trend Micro program, you may reply to this thread and help you through it.
