I have installed BullGuard Antivirus in my computer and since than i am facing some problem with hidden files and folders. All files and folder from my computer were appearing hidden but I somehow managed to get them back using Command Prompt but now whenever I open settings for folder option both show and hide options in hidden folders & file were stay marked. If I change it and open in again it a few seconds then it occur again. This is the first time I am experiencing this issue, there were no problem like this before. Can anyone guess what might be causing this issue and solution for fixing it??
