I had aproblem before with my PC. It got infected with this worm which is unknown. Whenever i will double click drive c:, a message appears which says "cannot find fs6519.dll.vbs" somthing like that. I followed the steps given in one of my thread and it was gone. Now, i experience the same problem with my flash drive. How do i get rid of it? An easier way please because the intructions given to me by momok takes much time. Thanks in advance!
