Trying to open a webite

Hello Terry,
Thank you for reaching us with your concerns. May I know if the issue is resolved when AVG protection is disabled? Right click on AVG system tray icon and toggle the On/Off slider to disable AVG protection.

Sorry, can't find how to disable AVG protection.  But, my sister has a different protection system and she is getting the same message when she opens the website.

Trying to open a local website and get this message:
"The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted'
I just opened it last month, don't know why I'm getting it now.

Thanks for letting us know.
If you need anything else, do not hesitate to let us know.

I haven't plugged in anything, such as a USB or SD card. 

I just tried the site again, and now its there and working, so must of been something to do with the web site itself.  Thanks for all the help tho.

Terry, sometimes, when you plugged in an external hard drive, USB flash drive, SD card or some other storage devices into your Windows computer, Windows prompts "You need to format the disk in drive G: before you can use it. Do you want to format it?"
You might click Cancel to refuse to format the disk or card if there are some important data files. Then Windows will prompt "Drive G:\ is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted." This is how usually "The volume does not contain a recognized file system" error occurs in Windows 10/8/7.

Are you sure that it appears when you try to load a website? Please let us know which website it is and provide a screenshot of the error message.
