I made the mistake of letting a friend connect one of my external drives to his laptop without knowing that he wasn't running any anti-virus software. As soon as I reconnected it to my own netbook, I got a virus warning. Fortunately, my anti-virus seems to have stopped anything from getting through to my computer itself, and I ran the anti-virus on my external drive, as well as Malwarebytes, several times and it now appears to be clean. However, all of my folders have been rendered invisible. I was able to view them again by changing my settings to allow hidden folders and system folders to be viewed, and everything seems to be there, but it would be nice to get things back to the way they were. Is there any way to do that?
