I had Trend Micro Worry Free Business installed. I uninstalled it via the control panel (because previous experience had shown that Sophos couldn't remove it). Re-booted the machine, tried to install Endpoint, failed at Third-Party stuff.
Downloaded a Trend Micro Uninstaller, ran that, try sophos still failed.
Installed Trend, then removed Trend.
Tried Sophos, still failed. Is there a way to bypass the thrid party check during install?
