Why my pendrive is behaving abnormally?

Recently, my pendrive started to behave abnormally. I discovered that every file I keep there, disappears and forms a shortcut. I even found few malwares when scanning by my Avast! Internet Security 8. I moved them to chest, but still the issue's not solving. I don't know how in the world these got there, I plugged the pendrive only in safe computers protected by internet securities.

My pendrive is Transcend JetFlash 350 8GB.
