Uninstall failed

Hey everyone,

we wanted to uninstall Sophos Endpoint Defense.

With the Enterprise Console we put the Targets we want to uninstall in a policy Group with tamper protaction disabeld.

The uninstallation does not go through properly.

We would be very happy to receive help.

Here is a log that i found in the %temp% folder:

  • You seem to uninstall all components only fail to unload the driver. Been a while not using Sophos Enterprise console, so i dont remember the driver names. Try to open a cmd with Admin rights and check drivers with "fltmc". Learn exact name of driver if you can and try to manually unload it "fltmc unload somedriver". if it still gives error, then you will need to reboot the device and try again. (in case its hooked to kernel it wont let go unless reboot) Also you can try to reboot and run uninstaller again.
