I have a zion 256 mb pen drive. some days ago, i took it 2 my college computers, for transfering some files. It (the pen drive) worked fine for a few days but then i found a folder named 'music' in it, which i had not made. I deleted it but it again came back. Then I formated and scanned my drive with avast antivirus but it didn't show any problems. Now, when I enter the drive by double clicking on the pen drive, an application runs for a very short while and then my av shows that there is some 'trj' in it. I've tried to format it again n again, but the problem persists. Please help me i'm in big trouble coz i need my drive badly.
