tried to run /opt/COMODO/post_setup.sh and it says "Please run this
script with adminstrative priviledges even though I am logged in as an
adminstrator.
Please note that, even you logged in with your admin user as you say this means nothing in Linux, even you have admin privileges, you in really not using those privileges and in really system treats you as a normal user UNLESS you use sudo or su to root.
There are two ways to run administrative applications in Linux. You can either switch to the super user (root) with the su command, or you can take advantage of sudo.
Read this introduction to SUDO.
Back to your question
Please run this script with adminstrative priviledges
Then you need to call your script using sudo
:
sudo ./opt/COMODO/post_setup.sh
File System Filter Driver Not Loaded.
Refer to this post in the Comodo forum
