I noticed there’s a Trustix folder that was probably created during the installation of Comodo. Can it be deleted? There nothing in the folder/subfolders except a .p7b file.
Before Comodo firewall there was Trustix firewall. Due to certain complications Comodo were unable to change the name from Trustix. You can get more information from the following topic:
This folder contains the licence for the software so it is best not to delete, or you will loose the licence.
