Problem opening folder in pen drive

Hello,

I have a friend running Windows Vista and she has a pendrive of 2GB. Now she is having the problem to open folder on it and for succeeding in opening it she must right click and run as administrator, otherwise it won't open it.

There is only one user on the PC thus the user account is the Administrator. She already tries to format the pendrive several time with the same results. Just a little info the pendrive was put on a laptop two days before with Windows Vista.

What can be done to repare this little problem?
Thanks in advance for any help

Need help please!!!

The pen drive may have failed. If it cannot be read on another PC (preferably running XP not Vista) she has lost the data. No data should be entirely trusted to a pen drive, just for a start, they are rather easy to lose ! Teach her something about backup.

Transfer all data on HDD then reformat the pendrive

This sounds like a virus, as far as I know you can't "run" a folder as administrator, it might be a program that LOOKS like a folder. Try to look at it with DOS. Find out what drive letter your pendrive has (e.g. "F:", and do as follows:

Press the start-button and type CMD and press enter.
Type

dir x:

to list the contents of your pendrive (replace x with the appropriate drive letter.)
If the folder you're unable to open shows up with .exe at the end it's a virus, and you should run a virus scan on your pc and your pen-drive. Also look for files named autorun.inf, could be a virus too.

Ok will try!!!
