remove webroot and addons-config netshare

I just ran into this issue with my ReadyNAS Duo and would like to confirm the following for anyone else that experiences it. I installed - and subsequently de-installed - the Transmission addon which resulted in "webroot" and "addon-config" phantom shares being left on my device. I had the same issues discussed throughout the thread re. not being able to see the shares in Frontview, and I could not delete them via normal access to the device (as an admin user via AFP or CIFS). Firmware reloads and/or updates did not correct the issue and I was loathe to reset the device to factory settings forcing me to backup and re-sync 2TB of media. I finally loaded the addons suggested (Enable Root SSH Access; Toggle SSH) and accessed the device via SSH using Cyberduck on my MacBook Pro. After deleting the "addons-config.conf" and "webroot.conf" files found in /etc/frontview/samba/addons, everything is back to normal and at least I learned how to SSH into my ReadyNAS Duo in the process...nerve-wracking as it was. My thanks to all the other posters for their help and info here.
