I read in another thread re the disk space being taken up by the Webroot Logs.

Checked the WRData folder was about 10GB.

I uninstalled Webroot, deleted the WRData folder, clean install and new folder is 8MB



I had never looked at the install options previously and noticed that there is an option to install to a scrambled folder name with the Webroot executable given a different name so if a threat automatically goes to the default Webroot install location it cannot find the Webroot executable and disable Webroot.
