I know this isn't the greatest place to ask for computer help, but since I haven't been able to find any information anywhere else, here goes.
My flash drive has a file that keeps appearing on it no matter how many times I delete it. It's called "help.vbs", and it's a Visual Basic script file.
What this file did was "remove" any files (pictures, etc) that I placed in the root folder of the flash drive, and replace them with shortcuts. (?!) I eventually discovered that it was actually only
hiding the originals (i.e. marking them as hidden), so I decided to eliminate that problem completely by moving those files to folders on the flash drive.
Now, I've still got the file popping up after I delete it. I tried editing the file to make it not "hidden" (which is why I can only see it here, and not on the computers at the local community college), or to remove all the code - leaving a 0 byte file - but it keeps reverting to what it was originally.
I'm worried that the file might cause more permanent damage, seeing as how a very similar situation with a different flash drive ended up with everything on that drive being lost (replaced with non-working shortcuts to the folders, which had been deleted). Unfortunately, I haven't found any information online, because Google doesn't 'count' periods, and my searches only lead to people asking for help on Visual Basic or Vacation Bible School stuff.
I tried scanning the entire flash drive and the file itself with AVG, but it didn't detect any infection.
Any help on this would be greatly appreciated!
EDIT: Just noticed this file is also popping up in my computer's Startup folder. Tried deleting it there, keeps coming back.
