After installing Bitdefender Antivirus Plus 2018,I can't change Windows hide folders options.But in safe mode,it works properly.
Using Windows 10,With Creators Update Installed,(x64 Version)
This is a long-standing issue.
I have had this problem ever since I first started using Bitdefender (many, many years ago).
This happens everytime Bitdefender detects a virus.
The only way I've found to re-enable the option, is to restart the PC and to try again.
