Read-only location - Profile folder locked - ESET Browser Protection
I just found the solution to this upsetting problem, thus I am sharing the relevant information with the community.
To solve all these issues, you have to disable ESET Browser Protection for all browsers, which is the second option underneath the Enable Safe Banking & Browsing option in the ESET configuration settings.
ESET - Setup - Advanced Setup - Browser Protection - Safe Banking & Browsing - Enable Safe Banking & Browsing - Browser Protection - Secure All Browsers
