Hello,
My flash shows files named porn,sexy and secret. Isuspect they are viruses since Ikeep on deleting them and they reappear. How can I remove them without losing data?
You could always copy off the data that you want and reformat the device but, as Hawkeye22 wrote, there is a good chance that the problem is on the computer by this point. So take his advice and treat the whole computer.
